Collected By the Crow by Delilah Dare

The melody of her pulse awakens dormant instincts…
Instincts he refuses to deny.

Crows have been following Cassandra everywhere lately. The same week she receives a mysterious letter claiming to have the formula her team has spent months looking for, a murder of crows swarm her windowsill with shiny trinkets until she follows them into the woods.
Qadaire pioneered the scientific revolution from his hidden castle. He’s not used to being told no. When his feathered friends lead the curvy pathologist to his doorstep, dark urges roar to life from deep within his cursed soul. He must unravel the woman who dares to defy him.
Cassandra is married to her work. She has no room for distractions . . . including the dexterous vampire who leaves her breathless each time he wraps her around his fingers. Breathless, and wishing for just one kiss.
