Their Own Sanctuary by Lacey Carter Andersen

Medusa met her gargoyles. Fell in love. And had her babies. Now what?
In the sanctuary, life’s never boring. Between keeping up with twins, and keeping things hot with her gargoyles, Medusa has a chaotic life. Which she loves!
But what happens when a strange creature is found hurt in their sanctuary?
Her gargoyles don’t trust it. Her daughters love it. And her feelings about it are complicated–except that she’s bound and determined to prove her smug hotties wrong.
