Accepting Submission by Kris T. Bethke: When Asher loses the ability to shift into his bear, he heads to a wolf pack with the hopes that Alpha Trey can give him what he needs.

Gym Slave by Gordon Phillips: Marc joins a new gym to expand his personal experiences, but finds these and more in a back-lot encounter from which he is rescued by Anatole, a gym staff member. In a journey of captivity and degradation, Marc discovers disturbing aspects of his own nature and must choose between ordinary life and that of a "Sub" in a relationship that challenges his deepest values but feeds his deepest passions.
Leather and Tea in London by K.L. Noone: Retired secret agent Ben will do anything for his husband. So when Simon's brother needs help, Ben and Simon head to London. But this new mission only reminds Ben of his past. Simon wants to help Stephen, but being back home stirs up ugly memories for him, too.
