Serpent's Kiss (The Beauchamp Family #2)

Alternate cover edition can be found here.

Just as things have settled down in the off-the-map Long Island town of North Hampton for the magical Beauchamp family, everything gets turned upside down once more when Freya's twin brother Fryr, or "Freddie" as he's called now, returns from Limbo with shocking news - that it was none other than Freya's fiancé, Killian Gardiner, who set up his downfall.
He begs Freya to keep his presence a secret, even from their own family, but somehow the irascible Freddie is still able to conduct many affairs with the town's young lovelies from his self-imposed exile. Until he falls for the wrong girl.

While Freya tries to keep her brother from exacting revenge on the man she loves, Ingrid has her own problems. Her human boyfriend, Matt Noble, becomes entangled in a complicated investigation, and when the magical creatures at the center of it come to Ingrid for help, she has a difficult choice to make.

To top it off, a dead spirit is trying to make contact with Joanna - but does it mean to harm or warn the witches? All hell breaks loose at the family reunion over Thanksgiving, and much mayhem ensues, but when the culprit behind Freddie's imprisonment is finally revealed, it may already be too late to staunch the poison that's been released by the serpent's kiss.
