I came across this good-condition hardcover on the charity-sale shelves at a local Hannaford's, and had to pick it up. It's about an 8th-grade girl who is trying to support herself and her emotionally-fragile mother on a very limited income. Her late grandfather left a puzzling message about a larger inheritance, if only Theodora can figure out what it means... The search leads to works of art stolen in WWII, with references to the "Monuments Men" and their attempts to rescue priceless art from the Nazis. But was Theodora's grandfather on the side of the rescuers or was he one of the looters?
The story touches on the liberation of the concentration camps too, and leads Theodora through tangled webs of family history - and back around to a coincidence that, while it might be a bit too pat, made for a satisfying conclusion.
The author explains that the story was inspired in part by The Forger's Spell
