Under Her Roof

My name is Gillian and I have three problems:A fallen tree through the roof of my family's remote island cottage.
A sister trying to sell said cottage out from under me.
A dead body in the living room. Sadly, it's not my sister's.
Actually, make that four problems: my ex, Amanda, just showed up uninvited. Apparently, she's a spy, undercover to investigate the luxury wine auction hosted by my conniving sister.
We've got no connection to the mainland and a murderer on the island, so tonight Amanda and I have three missions:Find the killer
Stay alive
Escape by sunrise
Actually, make that four missions: Do not fall in love, because apparently Amanda and I are far from over.
