Kraken the Case. Kraken's Cult, #1

Half kraken, half fae Environmental Police Agency enforcer Iolani Lionheart has everything anyone could want: power, money, beauty, family connections, and enough degrees to wallpaper a mansion. Too bad that's all anyone ever wants her for. To most people, Io is a fling, a favor, a weapon, or a very impressive name to drop. She is too powerful, too strange, too arrogant. too much. Not the sort of person someone keeps.
Which is unfortunate, because her clingy kraken heart and indulgent fae nature would very much like a mate-or mates-to hoard. After her latest power-hungry lover betrays her, Io is more than ready to escape into work. An ocean-side pollution case in Florida sounds perfect. Saltwater, sunshine, a simple investigation, and maybe a pretty distraction to help her forget her terrible taste in partners.
Then the "simple" case starts looking a lot more dangerous. Someone is poisoning the local waters. One of Io's exes has appeared to make trouble. And the shy sea sprite barista Io can't stop flirting with may be the first person in a long time to see past the money, magic, and tentacles. if only Io can earn her trust in every form she wears. Unfortunately, patience has never been Iolani's strong suit.
Neither is not eating people who piss her off. Kraken the Case is a snarky paranormal reverse harem with budding romance, a genderfluid kraken-fae heroine, monster magic, tentacles, found family, and the start of a building polyam series set in the world of Gesa's Menagerie. Series contains MF, FF, MM, and NB/intersex pairings.
