I did enjoy Book 3 a bit more than I did the previous two entries in this M/M romance series. Although the short length bothered me yet again (I still maintain that this series should've been released as two 250-page books rather than five 100-page books), at least the story picked up some steam and things started becoming more interesting.
The trip to the unearthed temple, Gabriel's visions of the past, finally some revelations about Cthulhu (the massive, tentacled creature that has been alluded to previously), Gabriel's discovery that he is a "Caller" (a merman with the ability to summon Cthulhu), Corey finally meeting Casillus were all events that gave this book a sense of excitement the prior books lacked. This book was an undeniable page turner and had me eager to find out what was going to happen next, something I hope continues with Books 4 and 5.
Although I prefer slow buildup to the kind of insta-love that occurred in this series between Gabriel and Casillus, I nevertheless found myself swooning at the utter devotion to Gabriel that Casillus has shown. After all, who wouldn't want a good-looking prince who tells you he'll never leave you and actually means it?
