This Sweet Magic - Rosewood, #1

When Andrew unexpectedly inherits a commercial building from his estranged grandmother, he's certain his problems have been solved. Once he sells the building, he'll have the money to help his sister and start a new business. Or so he thinks, except one of his new tenants is determined to do everything he can to stand in Andrew's way. As Rosewood's resident witch and self-appointed guardian, Damon spends his days baking cupcakes and casting charms to protect his friends and neighbours.
Devastated by the death of his longtime mentor, his world is upended even further when his sexy new landlord's plans threaten everything he holds dear. Andrew wants to get out of Rosewood as quickly as he can. Meanwhile, Damon can't understand why Andrew is determined to destroy his home. If they want to be together, they'll have to let go of the past and share their secrets. Because magic happens when you least expect it.
