I was given a free review copy of this book by the author in exchange for an honest review. And I have to say Fantastic, I so love the Department 89 Books, Major Decker is a woman you don't want to mess with, and shes taking her small team and heading to Russia to get their man back. A fast paced action packed, explosive energy story, well worth a read. Look forward to the next book this year 'The Traitor'. And if you have some time check out Assassins Child by Mark O'Neill, it gives you a small idea of early life Decker.

This is the best of the series so far. The characters become more three dimensional, and recent events concerning Russia make the story even more poignant. The quality of writing is better than ever. This book sucked me in from the word go, and Major Sophie Decker has just become one of my favourite literary characters.

Gewohnt spannungsgeladen kommt diese Story daher und bringt die uns bereits aus den ersten beiden Bänden vertraute Agentin Major Sophie Decker mit ihrem Team nach Russland, wo sie einen Kollegen aus den Klauen des russischen Geheimdienstes befreien soll.
Natürlich wird auch diesmal wieder ordentlich geballert und es fliegt einiges in die Luft, aber das Team wird auch menschlich auf eine harte Probe gestellt. Der Autor versteht es hervorragend, die Story mit einer Prise Humor zu beleben, während man sich fragt, wie die Dinge auf höchster Regierungsebene eigentlich wirklich gehandhabt werden. Wenn man sich in der Welt so umschaut, erscheinen die Ansätze in diesem packenden Thriller gar nicht so weit hergeholt.
Obwohl jedes Buch der Reihe für sich steht, ist es angenehm, die gleichen Personen wieder zu treffen und tiefere Einblicke in ihre Persönlichkeiten zu bekommen – so verstörend das auch in manchen Fällen sein mag.
Wer Spannung, Action und taffe Frauen liebt, wird an diesem Buch jede Menge Freude haben.
