FREE: Up in Smoke (Glock Grannies Cozy Mystery Book 1)

Just picked this free novel up myself so I cannot tell you yet if it is a good one. Reviews seem very mixed.

This is the Amazon blurb:

"Nikki is a flirtatious six-time divorcee. Geraldine is her quirky grandmother. Mix in a bunch of gun-toting grannies, an outrageous retirement home, and an unsolved mystery and there's bound to be some excitement. Follow along as Nikki and the cast of retirement home vigilantes work to solve the mystery before everything goes up in smoke."
