Splinter

A sudden attack, a daring response... On the shore of Oslo Fjord, teenagers Kristian Thorsen and Helene Berg
watch in shock and horror as their world is upended by a Nazi invasion.\nDriven apart by tragedy and trauma, Helene and Kristian take different paths
to join the Resistance, but fate soon swirls them back together. Like many
who rebel against the invaders, they must become spies and covert warriors
on the fly, making huge mistakes along the way. Yet even on such a tortuous
path, they are surprised by moments of grace.\nWhen Helene manages to steal secret Nazi plans for precision bombing of
England, Kristian launches a life-or-death mission to get this crucial
intelligence across the North Sea and into Allied hands. He'll try anything to
defeat the fascist occupiers—and to win Helene's heart.
