Mad Love by Suzanne Selfors

Alice figured her teen life would be normal and simple like everyone else's, but what she didn't expect was to be running a house on her own, buying groceries, paying the bills and lying to everyone. The mystery question was: where is Alice's mother? Other than that, why is that strange boy claiming to be the mythological god, Cupid? And how does Alice's crush Tony feel about her lying to him?
