Little Celeste — Dawn McNiff

Eleven-year-old Shelley only leaves her bedroom for two minutes, but when she gets back, there's a real, true-life, lavender-eyed baby on her bed. It's far too noisy, smelly, and heavy to be a ghost baby so whose is it? It can't be her mom's Shelley would have noticed but it's not like she's around for Shelley to ask, anyway. She's too busy trying to get her horrible ex-boyfriend Scott ("the Toadstool") back, who Shelley definitely does NOT like as much as her mom does. But someone's got to look after the baby, and give her a name. "Celeste" sounds good (in fact, it sounds kind of magical), and so Shelley and little Celeste embark on some rather messy adventures, gain some new friends, and realize that maybe some wishes can come true after all."
