During a two-week stay at Grammy and Granpa's farm in the summer of 1944, Molly spends lots of time with her good friend Anna Schulz, the daughter of German immigrants who live on a neighboring farm. When Aunt Eleanor, now a WASP pilot, stops for a visit while ferrying a warplane from one airbase to another, a security check uncovers anti-American propaganda stashed aboard her plane. The FBI interrogates Eleanor but quickly zeroes in on another suspect—Anna's 17-year-old brother Max, who works at the local airfield. Though Anna knows her brother is loyal to America, she fears he'll be sent away to an interment camp as an enemy alien, as other German-American friends have been. Molly and Anna decide that the only way to clear Max is to find the person who is smuggling propaganda. With lots of daring and a little luck, the girls manage to finger the real culprit…but they discover that that may not be enough to save Max. In a poignant ending, Molly realizes that wartime, even on the home front, changes friends and family forever.

Molly wishes she and her friend Emily had an exciting volunteer job that really helped in the fight to win World War Two. Instead, they're magazine delivery girls at Oak Knoll Hospital. Soon, however, Molly and Emily start to suspect that something very un-patriotic is going on at Oak Knoll—and their snooping leads them deep into trouble!

Molly still does her her patriotic duty to help America win World War Two, but in the spring of 1945 she's weary and troubled. Dad is home safe . . . but he seems different now. Her favorite Red Cross leader abruptly quits. Her archrival, Ronnie Vanko, is driving her crazy. And now someone is sneaking into the backyard shed and messing with the scrap she's collecting for the latest wartime drive. Who is the intruder: Ronnie, her own brother Ricky—or a prowler she spied in the night? This book includes a richly illustrated "Peak Into The Past" essay.
