If I could give this book more than 5* I would. I became totally invested in the characters, it was brilliant. So many twists and turns, it kept me hooked to the very end. I confess I didn't see the ending coming at all.

I really enjoyed Cruz’s idea of science regulating everything, including love, for the Vaelteurians and Mavis’ struggle to break with that tradition. Cruz also interlaces a good thriller with the romance, blending both with fast paced and steamy description perfectly! This one’s perfect for both sci fi and romance lovers!

A mix of sci-fi, mystery and romance; a story of love that transcends the vastness of the universe, what more can you ask for?

The plot of twists are maintained throughout the book. Must read if you're a fan of romance+thriller genre.

A very intense story. Following his extreme reactions, her total confusion and then an extreme and interesting continuous plot-twist. I am so glad I continued reading to the end.

This is a story that touches on so many levels that appeals to different genres.

The book was a series of revelations that will make you yearn to turn the next page just so you will know what happens next. It was an absolute delight to read. The plot was unexpected but well thought-out and unlike any other book I’ve ever read.

What an awesome read. A heart wrenching thriller about love, loss and mental illness. I couldn't put it down. Have your tissues ready and prepare for the mind-blowing ending that you won't see coming.

Chroma Hearts by Mayumi Cruz is a gripping and thought-provoking story about fighting for love against mental illness, with a side of crime solving.
