The Fall of Io

The superb aliens-in-your-head SF sequel to the wildly popular The Rise of Io, by the author of The Lives of Tao series.

“Years after a killer debut, Wesley Chu keeps leveling up. Storytelling that seems so effortless you never see the punches coming.”
– Peter V Brett, bestselling author of the Demon Cycle series

When Ella Patel’s mind was invaded by the Quasing alien, Io, she was dragged into the raging Prophus versus Genjix war. Despite her reservations, and Io’s incompetence, the Prophus were determined to train her as an agent. It didn’t go well. Expelled after just two years, Ella happily returned to con artistry, and bank robberies. But the Quasing war isn’t done with them yet. The Genjix’s plan to contact their homeworld has reached a critical stage, threatening all life on Earth. To complete the project they need Io’s knowledge – and he’s in Ella’s head – so now they’re both being hunted, again.

“Damn, this is a great book. Wesley Chu may have created his best character yet with Ella – a scrappy, savvy street urchin, who he tosses into a world of hidden aliens, political maneuvering, and possible treachery.

– Ramez Naam, author of Nexus and the Philip K Dick Award-winning Apex

“Ella Patel of Crate Town is my favorite kind of hero, a young person struggling to survive on a diet of tough living and petty crime who gets swept up in world-spanning intrigue and danger. Wesley Chu’s funny, confident writing never sacrifices good science fiction world-building for the sake of action. While the bullets fly and knife blades flash, Chu also gives us body-jumping aliens and poignant characterizations. The Rise of Io is a fast and furious ride piloted by an author rising to the top of his field.”
– Greg Van Eekhout, author of California Bones

“This is a fun, fast-paced, adventure slash science fiction… every time I read a bit, I finished with a smile on my face.”
– Eric Christensen

“Great characters, twists, suspense and grins – I dug this one so much. He keeps the magic of the Tao books, reinvigorates it and expands it. I expected Chu to deliver just what fans wanted without it being a case of ‘second verse, same as the first,’ I just didn’t expect it’d be this good.”
– Irresponsible Reader

“Top to bottom…total FUN.”
– Shelf Inflicted

“Fans of Cory Doctorow, Suzanne Collins and Meljean Brook will relish Chu’s latest, a thriller with a sci‐fi bent.”
– RT Book Reviews

“It puts awesome women in the lead roles; has a nicely diverse cast; and tells a story that’s not only a thrill-a-minute, but focuses on some of the ugly truths about the world that need a bit more focus put on them, if only because they need to be fixed to make the world a better place. Even better, it all comes wrapped in a fun, sci-fi near-future thriller package… If the reader is hankering for a Black Widow movie, but with a healthy helping of representation of the kind we’re unlikely to get from anything coming out of Hollywood right now, then this five-star book is going to scratch that itch.”

– Litstack

“It defies conventions while engages readers in hilariously heartfelt narration. I could not recommend this book more.”
– Better Books and Things

“A great read. It was filled with all of the things I love in a book – action, sympathetic and interesting characters, political intrigue, a well thought out and believable setting, and enough humor to keep me chuckling, but not enough to pull me away from the seriousness of the adventure they were on. Like I said earlier, this book needs to be a movie.”
– The Geekiverse

“It was like reading a summer blockbuster in book form. And the banter was amazing! Chu definitely has a gift for writing hilarious and action-packed stories!”

“The author won me over with Ella, a feisty, street-smart heroine. Her snarky attitude and just as often, her bullheadedness became the high-point of this new series.”
– Controlling the Transmissions

“My worry with this book was that it was a case of an author not being able to let go of the universe they created even when there is no more story to tell. These are almost never good. Thankfully, this was 100% not the case here.”
– Book Geeks Uncompromised

“The Rise of Io by Wesley Chu returns to Chu’s world of Prophus and Genjix but with a new set of characters who are strong and wilful and a delight to read.”
