10 The Fifth Season (2015 – 2017)

Written by N.K. Jemisin

Cover art for the fantasy novel The Fifth Season by N.K Jemisin  

The Broken Earth trilogy by N.K. Jemisin is a rare series that perfectly blends fantasy and sci-fi. The fantasy aspect is quite evident since the books have talking stones and people with the power to manipulate earth textures. However, the most impressive part about The Broken Earth trilogy is how N.K. Jemisin integrated science fiction with the fantastical aspects. The Stillness is the only continent left on Earth, thousands of years from now and after many catastrophic natural disasters that have reshaped the world known as Seasons.

Given the circumstances, The Broken Earth trilogy needs a lot of thorough world-building and consistency, but N.K. Jemisin successfully achieved this goal while delivering a compelling narrative with complex characters.

The Broken Earth's fantasy characteristics were born from a scientific accident, and the supernatural and science are forever entwined. Given the circumstances, The Broken Earth trilogy needs a lot of thorough world-building and consistency, but N.K. Jemisin successfully achieved this goal while delivering a compelling narrative with complex characters. The series also touches upon themes of motherhood, oppression, survival, and love. There is nothing quite like The Broken Earth trilogy; it is uniquely ambitious and pays off immensely.

The book series also introduces advanced technology that does not currently exist but could be possible in the future.

8 The Hunger Games (2008 – 2010)

Written By Suzanne Collins

7 The 5th Wave (2013 – 2016)

Written By Rick Yancey

The 5th Wave is a trilogy by Rick Yancey that tells the story of a futuristic world in which aliens take over Earth in waves. Although aliens are often explored in science fiction, Yancey's series is different because of the systemic way aliens take over Earth. The aliens in The 5th Wave trilogy also introduces the 12th System, technology that subdues humans by implanting them with special nanobot technology to become like the aliens. Rick Yancey crafted a story rooted in possible reality; everything that occurs is not a far stretch of the imagination, incorporating real themes from today's world.

6 Jurassic Park (1990 – 1995)

Written By Michael Crichton

Jurassic Park is a duology by scientific writer and filmmaker Michael Crichton. Although there are only two books, Jurassic Park became a multimedia franchise with several blockbuster movies, animated TV shows, comics, merchandise, and theme park attractions. However, the real gem is the original duology. Michael Crichton did not write about fantastical dinosaurs; he provided a scientific explanation as to how humans were able to bring dinosaurs back. His extensive background includes literature, biological anthropology, and medicine, which all aided him in writing this epic series.

Reading Jurassic Park and its sequel, The Lost World, illustrates the time, dedication, and research that Michael Crichton put into crafting these books. Not only is the premise for Jurassic Park thoroughly established, but the characters and dynamics Michael Crichton created are also compelling and complex. It is only a shame that the film franchise did not follow the books as closely as they should have. Jurassic Park might only have two books, but Michael Crichton built an ambitious and broad universe.

Written By Micaiah Johnson

The Space Between Worlds By Micaiah Johnson

The Space Between Worlds by Micaiah Johnson is set in a multiverse world with parallel universes. However, there is a catch—one can only travel to a parallel universe if their counterpart in said universe is already dead. The book follows Cara, who can travel almost freely because most of her counterparts have ed away. She leads three different lives that could not be more different from each other. The premise for The Space Between Worlds is risky and ambitious because it can easily fall apart. However, Micaiah Johnson succeeds because each setting serves a different purpose for Cara.

4 How High We Go in the Dark (2022)

Written By Sequoia Nagamatsu

How High We Go In The Dark By Sequoia Nagamatsu

How High We Go in the Dark by Sequoia Nagamatsu is about a doctor who accidentally releases a plague that devastates humanity to the brink of extinction. The book takes place across hundreds of years in different scenarios to illustrate how humanity adapts in the most dire circumstances. A story like How High We Go in the Dark cannot have one cast of characters; it needs multiple plots to portray humanity's fight for survival. The novel works because Sequoia Nagamatsu connects each segment through common themes such as grief and loss, tied together by survival instincts and willingness to endure.

3 Brave New World (1932)

Written By Aldous Huxley

Brave New World By Aldous Huxley

Brave New World is a sci-fi dystopian novel that takes place 500 years in the future when the concept of the family is extinct, and people are born and raised through artificial wombs, then classified based on their physical and mental abilities. Aldous Huxley set out to create an ambitious narrative with the various themes he wanted to explore, but it worked because of the two protagonists. There is Bernard Marx, who does not conform to society, and John, born naturally and raised by a single mother in a community that has not transitioned into Bernard's world.

Brave New World portrays Bernard Marx's desperation to leave his society, contrasting John's desperation to . The dystopian world that Aldous Huxley created covers themes such as motherhood, conformity, societal expectations, sexuality, and reproduction. Brave New World explores and unpacks various aspects of these themes, but Huxley's ambitious novel pays off because of Bernard and John's parallel trajectories. Once society accepts Bernard, he is ousted against his will, and once John s this futuristic society, he cannot tolerate it.

2 Binti (2015 – 2018)

Written By Nnedi Okorafor

Binti By Nnedi Okorafor

Binti is a trilogy of novellas by Nnedi Okorafor about the titular character, who attends Oomza University, a school where various species across multiple galaxies can attend. Outerspace, including other planets such as Mars, often frequents sci-fi, but Binti is ambitious because of how Nnedi Okorafor entwines various humanity-related themes in the trilogy. These themes include otherness, knowledge, selfhood, and empathy. Although the Binti books are short, they work well for the narrative and what Nnedi Okorafor wants to explore in these novellas.

1 Remembrance of Earth's Past (2006 – 2010)

Written By Liu Cixin

The three books that make up the Three Body trilogy by Cixin Liu, including The Three-Body Problem, The Dark Forest, and Death's End

The Remembrance of Earth's Past trilogy, more known as The 3 Body Problem, is a series by Cixin Liu about an advanced species, Trisolarans, looking to infiltrate and invade Earth due to their home planet, Trisolaris, no longer being inhabitable. Trisolarans discover Earth because Ye Wenjie uses the Sun to echo sounds across the universe, which reaches Trisolaris. Remembrance of Earth's Past touches upon many themes relating to humanity, especially as humans attempt to defeat Trisolarans as they approach the planet.

The 3 Body Problem explores the Chinese Cultural Revolution, relations between various alien species, global power, revolution, colonialism, and scientific progress. What makes Remembrance of Earth's Past so ambitious is how the story spans thousands of years to illustrate how humans and aliens interact and how said interactions change over time. The premise can easily lead to a messy narrative, but Cixin Liu crafts an epic sci-fi narrative with complex characters without losing sight of the bigger story.
