Hail to the King by May Sage

Ryn is a mess: unruly hair, untidy apartment, paint under her nails and a broken spirit. She’s the irregularity in Desmond’s neat, perfect schedule.
When she decides to move away from the city and resign from her position in his company, he attempts to take it in stride, sign a severance package, and wish her good luck.
One problem: a king does not relinquish his future queen.

This book comes with a trigger warning. If you’ve read Ryn’s story in Deep Down the Rabbit Hole, you know it’s dark. Moreover, this book includes menage and bisexual scenes.
Disclaimer from the author: Kings of the Tower is a steamy romance series about women going down the rabbit hole, and figuring out that it’s fun in wonderland. Don’t expect them to change, or tame the men they love. Don’t expect the male protagonist to force them into anything.
