I truncated the full titile in interests of getting it all in allotted space. From the description:
"Flora knows better than to take shortcuts in her family home, Crackpot Hall--the house has eleven thousand rooms, and ever since her mother banished the magickal butler, those rooms move around at random. But Flora is late for school, so she takes the unpredictable elevator anyway. Huge mistake. Lost in her own house, she stumbles upon the long-banished butler--and into a mind-blowing muddle of intrigue and betrayal that changes her world forever."
This teen fantasy gets 4.3 stars from readers (35 of 'em), but two of them give it one star. Digitial list price is $7.95 for a respectible 435 pages.
