Blood Ruby: A Sandy Corrigan Thriller

by Thomas B. Cavanagh

Sandy Corrigan is back—smarter, tougher, and in more danger than ever.

What should have been a routine job for a real estate developer explodes into a nightmare when private investigator Sandy Corrigan stumbles on a murdered corpse. The police quickly target someone she loves, and clearing their name becomes her only option.

But this case is no ordinary investigation. To uncover the truth, Sandy must plunge deep into the hidden world of Central Florida’s homeless community—where secrets fester, loyalties are fragile, and every step could be her last.

A gripping sequel to the award-winning Diamond Cut, which was hailed as “fast paced and suspenseful” by #1 NYT bestseller Janet Evanovich.
