Summer in Orcus

"Summer is a perfectly ordinary 11 year old girl with a perfectly ordinary, needy, over protective single mother. Summer loves her mother and would never dream of running away, but wonders deep down if it wouldn't be nice to escape for a little while and do something adventurous...maybe? Baba Yaga comes along in her magical walking house and offers Summer her heart's desire. Summer has no idea what this might be, but with the lighting of a frog-shaped beeswax candle she finds herself transported to the strange would of Orcus with nothing but a weasel in her pocket. She's read a lot of fantasy books about people thrust into strange lands; but they usually seemed to have has some idea what they were supposed to do there." -- back cover
