Dragon Mate’s Secret by Serena Meadows

When the chemistry is too strong to ignore,
But the secrets are too big to hide…
Burning lust becomes bitter betrayal.

Michael knows that finding love is a pipedream. Following in the footsteps of the dragon-shifter ancestors who came before him, his job is to mate and continue his lineage—not waste time on distractions like romance.
Amy has one love in her life: teaching her students about King Arthur and the folklore of his court. But when her best friend Molly stops returning her calls, Amy leaves her reclusive life in New York and heads to Prospect Falls. Instead of finding her friend, however, she discovers Michael, a man rippling with muscle, charisma, and deeply hidden secrets.
Amy will do anything to find Molly, and Michael seems to be the only person with answers. The trouble is, Amy is starting to suspect that Michael is not the man he claims to be, and when the truth is finally revealed, no amount of chemistry will forgive his dark manipulation.
