Love's Last Battle (Barlow-Barretts #6)
Laura Browning

Her best friend and cohort in crime is pulling up stakes and moving, and the man who’s moving in is far from the kind, grandfatherly friend Claude was. Now juggling her double life is turning into a tangled mess, and just when it seems Morgan might be finding a way out of the morass, she becomes the target of domestic terrorists.
Her only hope rests with Nick Van Pel, a sexy former SEAL who spends as much time hassling her as he does heating her hormones.
