Each and Every Spark (Hardcover, 2026)

From the Edgar Award nominated author of What Happened to Rachel Riley? comes an engrossing, timely, and propulsive story of two girls in Paris--one living under Nazi rule in the 1940s; the other in present day--and the mysterious painting that unites them. Perfect for fans of The Bletchley Riddle and When We Flew Away.

Paris, present day. Penny Marks has never felt so alone. Forced to move to France for some fancy job her mom couldn't turn down, she's now miles away from her old life. If she hadn't quit art after all that drama went down last year, she'd at least have something to keep her mind off the fact that life back home is moving on without her.

Paris, 1943. Marie Bonnet has never felt so afraid. When the German army seized power over France, she and her sister Heloise watched their father get taken away, leaving them on their own. Then Marie finds evidence that Heloise has secretly been working for the French Resistance--a group of rebels determined to take the Nazis down--and while it has danger written all over it, she's desperate to join. Any small act of uprising could help their country...but it could also cost them their lives.

Penny and Marie's worlds collide when an old painting resurfaces in present-day Paris after decades of being hidden. Along with it is a note whose message may lead Penny to Marie...and the fate that awaited her.
