Tricky as a Thief by Kendra Moreno

Lambs will become Lions…

Robin Hood is retired. He’s lived his life of thievery and adventure and he’s ready to settle down in the Enchanted Forest for good. No one can bother him anymore. Not the merry men. Not the rich idiots angry he stole from them. Nothing and no one.
Until a woman steps from a magic portal and threatens him with a blade.
Jill Morris has spent years trying to escape her prison in the Underworld, and when an opportunity comes, she takes it. She certainly didn’t expect to find herself back in the Enchanted Forest so different from when she left. Nor did she expect the man who refuses to help her stop the flow of demons that follows. When strangers appear and request her help, she can’t decline despite having her own problems. Her home is in trouble and the evil spreading must be stopped.
The rot is taking over. The Followers of the Crimson Merge are rising. The Piper is leaving chaos everywhere he goes. Hades is sending death threats and love letters. There’s no other option for Jill than to face each problem head on.

Now if only she can convince Robin Hood to come out of retirement and steal one last time. . .
