Come to Papa by Matilda Martel

This grumpy man of the month wants to be a daddy.
Reclusive writer Felix Mercer came to Candy Cane Key to find silence but quickly discovered peace and quiet are overrated. Disgruntled and unhappy, he can’t figure out what ails him until he meets the town’s newest resident and self-proclaimed cat lady, Harlow Jane.
Harlow loves two things— Christmas and cats. When she reads an article about an island in the Florida Keys that celebrates Christmas all year round and with a long-suffering stray cat population, she knows she’s found her own personal paradise.
Felix is instantly enamored, and a casual acquaintance quickly becomes an obsession. Harlow’s hot little curves drive him to distraction. Her kind, nurturing heart confirms he’s found the one.
But Harlow’s on a mission to save the world— one cat at a time. She doesn’t have time for love, marriage, and babies.
Can the town grump steal enough sunshine to woo her stubborn heart?
