Carol Cassella's novel Gemini had me at its beautiful cover. Just kidding, sort of. What really drew me to this medical mystery meets love story was an endorsement from Where'd You Go Bernadette? author Maria Semple: "Once again, Carol Cassella has written a novel full of gorgeously rendered characters, fascinating medical detail, and tour de force plot twists. From its gripping first pages straight through to its stunning conclusion, Gemini is an unforgettable novel — a morality tale, a mystery, and a love story that will leave readers breathless."
