This book won me over, page by page. I didn't really know what to expect aside from it being an epistolary novel, which I haven't read many of. The start was a tad slow going, for me, as I got the hang of each POV and their personalities. The more their environments, passions and relationships were discussed, the more I was invested and ultimately hooked. This entire story felt unique to me; from the underwater living, family histories, to the childhood nightmares and fantasies.
The mysterious disappearance and end reveal has me upset that book 2 isn't out yet.

Thanks to Orbit and NetGalley for the eARC!
