Waiting on Wednesday: The Mastermind Plot by Angie Frazier (Published by Scholastic, March 1, 2012)
Suzanna "Zanna" Snow can hardly believe it: she's finally going to escape boring Loch Harbor, New Brunswick. She's received an invitation from her grandmother--the mysterious woman she's never met--to stay with her in Boston. Think of all the mysteries to be solved there! While she's curious about her grandmother, she's even more excited for the chance to be close to her uncle, the famous Bostonion detective Bruce Snow and her cousin Will, Bruce's assistant. Much to her chagrin, her grandmother enrolls her in Miss Lydia Doucette's Adademy for Young Ladies, where all things proper are taught. In the meantime, Will recruits Zanna to help when a string of warehouse fires can't be solved. Zanna gets some leads, the most interesting being the fires' possible connection to famous paintings. When a stranger starts following Zanna, she starts to wonder if all her snooping has caught the attention of the elusive arsonist.
I enjoyed the first book in this series, so I am looking forward to reading book two.
