This is book number 1 in the series but it’s like the star wars trilogy but you don’t need read 4-5-6 before 1-2-3. If you’re interested sci fi books then I can’t recommend this series of books enough. The opening of this book is what pulled me in straight away. Literally a full on action sequence. We are introduced to the Kreelans by the unfortunate accident by the humans who came into alien space. Next thing that happens is quite horrific. As the Kreelans board the human ship they slaughter everyone on board except for one person. They call them the messenger. Who has the delightful message to tell everyone what happend and what’s going to happen. The Kreelans are on their way and plan to destroy anything and anywhere the humans civilised. As Kreelans see every other race as an enemy. Kreelans was to wipe out any other race so they will be the sole race of the universe and make it pure. You cannot put this book down unless someone physically removes it from your hand and hides it so you can get on with those house hold chores that you’ve been avoiding. I would give this book a 10/10 as it was unstoppable read and the series is magnificent.
