Arcane Deception

When her grandfather wanders off, witch Kate Marshall enlists a handsome neighbor to help find Eli, who suffers from dementia. She doesn't know Mark Delaney is a magic-using undercover agent trying to bring down a gang of drug dealers with deadly spirit animals.
Soon Mark and Kate find themselves falling in love, even as he wrestles with lying to the woman he's fallen for. Unfortunately, the gang lord is having them watched, so Mark can't come clean.
When the gang lord kidnaps Eli and Kate to force her to collude in his crimes, she must trust Mark to help them escape, despite his lies, the risk to her heart and the threat to her beloved grandfather's life.
