Publisher Description

INSTANT USA TODAY BESTSELLER!

The rebellion’s fight turns into a battle of the heart in this pulse-pounding conclusion to the Crimson Sails trilogy by New York Times bestselling author Katee Robert.


Nox has been steadfastly working for the rebellion for years. They don’t ask for much in return, except for one crucial condition: their ex, the noble Bastian, stays as far away from them as possible. To say things ended poorly between them is an understatement . . . and it’s the only relationship Nox has never quite recovered from.

But now the rules have changed. Siobhan, the rebel leader, has emerged from hiding to tell Nox that Bastian’s been taken captive and the secrets he holds tight are in danger of being revealed. The fate of the entire rebellion now rests on Nox and Siobhan’s ability to rescue Bastian from a Cŵn Annwn ship.

Saving Bastian is only the start of their hardships, as the trio is tracked by ferocious pirates across Threshold. And Nox’s complicated relationships and entanglements with Bastian and Siobhan put not only their life at risk but their heart on the line.

Rebel in the Deep Reviews

3.0
“I loved the first two in this series but this one was disappointing. I didn't care for any of the characters in this one. It was quite bland and I lost interest. I finished it just to say I've read the series. Unfortunately this one fell so short. The characters were boring and nothing really stood out about them. Her other series are much better.”
“Definitely more action packed and kept my attention than the second book. Glad the series is over though”
“Rebel in the Deep had a lot of potential, and while there were some strong moments, overall it left me feeling a little in-between. The worldbuilding was interesting, and I really enjoyed the unique setting beneath the surface—it gave the story a fresh twist. There were also a few action scenes that had me hooked, and I liked the glimpses of rebellion and courage in the characters. Overall, this was a decent read with creative ideas, but it didn’t completely hit the mark for me. It’s worth picking up if you enjoy adventurous, fantasy with a touch of rebellion, but it may not leave a lasting impression.”
“Not sure if Katee is done with this series, but I am. It was on better on audio but just not even close to my enjoyment of the dark Olympus series”
