Wow! 
 This book just hooked me. Hot, commanding alpha male with problems throughout his past and, of course, with commitment problems. 
 Neighbor to widow with two teenage girls. Starts a booty-call relationship. Gets more involved than planned for a variety of reasons. Stalker-type harrassment involving mafia-involved male who killed the heroine's husband prior to her moving to this new town. 
 Really liked this one.
