Vampire By Bliss by Cyndi Faria

A distant clan takes the new father from his mate, but Master Vampire Riley Sweetwater is up for a surprise when Tricia, his Faery Queen, arrives with a plan to strengthen her alliance with her husband.
Vampire Riley Sweetwater is master of two things: Vampire policy and satisfying his mate, Tricia, Queen of Faery. But lately, after the birth of their precious daughter, Riley’s struggling between finding alone time with Tricia and solidifying a difficult treaty, one that will take him away from his family for the first time.
Tricia may be the Queen of Faery and a new mom, but she’s not ignorant to the unquenched desires of her mate. She’s missing him too. She has a plan to not only surprise Riley by showing up at his meeting, thereby strengthening their alliance, but also to forge a deeper bond with her man…in every way possible.
