Furever in Love by Nicole Highland

Fresh from a dead-end relationship, Laurel Anderson knows life after college will be different. She’s landed a great job, bought her first house, and rescued a kitten from her local shelter; an all-black, fluffy kitten named Shadow. But when Shadow goes missing, her world gets flipped upside down.
Laurel fears all hope is lost, until her doorbell rings, and more than one pair of sparkling green eyes are staring back at her. Aiden Ross, the delivery driver she’s been trying so hard to resist, has saved the day and won over Shadow’s heart. But can he win over Laurel’s heart, too?
