The Lancelot Closes at Five — Marjorie Weinman Sharmat

Living in Camelot isn't all it's cracked up to be.
At least to Abby. It was hard to leave all her friends behind when her family moved to a new development called Camelot, a place so weird that the houses actually have names like Lancelot and Excalibur! But moving to Camelot wasn't all bad, because that's where Abby met Hutch, her new best friend.

It was Hutch's idea that they should sneak out and spend the night at the nearby model home, the Lancelot. She had it all planned. (That's what she claimed.) No one would know. (That's what she thought.) It was all going to be so easy.

Abby and Hutch's problems begin when the model home is closed for the night, but that's not where they end! Who knew that sneaking out for one night would cause this much trouble -- or be this much fun!
