Mrs. Smith's Spy School For Girls

"After a botched escape plan from her boarding school, Abigail is stunned to discover the school is actually a cover for an elite spy ring called The Center, along with being training grounds for future spies.
Even more shocking? Abigail’s mother is a top agent for The Center and she has gone MIA, with valuable information that many people would like to have—at any cost.
Along with a former nemesis and charming boy from her grade, Abigail goes through a crash course in Spy Training 101, often with hilarious—and sometimes painful—results."
