Blue Ring assassins — Book 3 [EPUB ebook] 

1944. The war has been raging for five years now. With each passing day, the death toll only seems to grow on all sides. In the struggle against the Third Reich, Hannah and Petra are doing all they can to aid the fight,  but with Heidi now out of action, it is proving hard to keep their focus on what — or who — they should be fighting against.

Despite their internal struggles, both Hannah and Petra are working hard to grow their organisation, all while undertaking several new missions from both the British and the US that will see them travel across war-torn Europe.

The end of the war still seems so far. Will the girls prevail, or will everything they have worked towards end in a cloud of smoke?
