Tempting Tiger by Lynn Hagen

Elijah has lived in Midnight Falls all his life. When his parents move to Florida for their retirement, Elijah takes over caring for his grandparents. He’s in way over his head. His granddad has onset dementia, and his grandma keeps calling him by his mother’s name. When Elijah ventures into Wild Tiger on one of his rare nights out, he meets Mason, and instantly falls in lust with the guy. If only his ex-boyfriend, Kyle, would leave him alone.
Mason knows the moment he smells Elijah that the human is his mate, and he vows to protect him from any harm—even if it means taking on a loan shark who has targeted Mason’s brother. He’s well aware of how volatile his relationship with Reid is, and he fears that the danger Reid now brings into their lives will only worsen the situation. Mason is determined to keep Elijah safe, but their enemies may have other plans.
