These are your neighbors. One is a killer.

Reeling from a very recent divorce, Frankie has moved into a glamorous London neighborhood. This is a new chapter in her life. She’s decided to put down roots with Blue, the beautiful Persian cat she left her marriage with.

But little doubts about her perfect new life start to grow, and when Blue returns one night from slipping into places he shouldn’t, Frankie’s concerns solidify. Two words are roughly scratched into his collar: help me. Unsettled and unwilling to ignore the incident, Frankie roots out an old unused “cat cam” collar. What slowly begins as a voyeuristic fascination with her neighbors and the secrets they’re hiding soon turns into a perilous quest for the truth that threatens to bring untold terrors to her doorstep.

A riveting thriller about the terrible secrets hidden behind the pastel-colored façade of one of London’s most upscale enclaves, Nine Lives is catnip for suspense readers everywhere and perfect for fans of modern classics like The Girl on the Train and The Woman in the Window.
