You can choose your home, but you can't choose who lives next door . . .

Twenty-five-year-old Kat Bennett has never felt at home anywhere, especially not in crumbling Shelley House. The other residents think she's prickly and unapproachable, but beneath her tough exterior, Kat is plagued by guilt from her past and looking for somewhere to belong.

Seventy-seven-year-old Dorothy Darling has lived in Shelley House for longer than anyone else, and if you believe the other tenants, she's as cantankerous and vindictive as they come. Dorothy may spend her days spying on the neighbours, but she has a closely guarded secret herself - and a good reason for barely leaving her home.

When their building faces demolition, sworn enemies Kat and Dorothy become unlikely allies in their quest to save their historic home; and even less likely detectives when they suspect that foul play is coming from within Shelley House . . .
