Kiss Me Now by Melanie Jacobson

He’d be the perfect guy…if he wasn’t trying to ruin her life.

Ian would do anything for his grandmother, so when Gran suddenly announces she’s leaving the family property to her pretty new neighbor, Ian is on the case. He’ll use every one of his sharply-honed skills as a private investigator to expose the gold digger and save Gran.
Brooke is living her best life far from the city and career that tried to destroy her. She’s happy spending her summer renovating the house she inherited and gardening with her elderly neighbor, Miss Lily. But when Miss Lily’s handsome—and obnoxious—grandson shows up, making wild accusations and dragging up Brooke’s past, Brooke must convince Ian he has her all wrong.
But what happens when their chemistry proves even more dangerous than Ian’s accusations?
