Amazing!! This book is great!! Tons of actions, an outstanding story and characters that we love and care for. This book take place after Hammerhead, and from the beginning it was a pleasure to see old characters back in action. A really good science fiction book! I always love the writing of that author, but this one is clearly is best so far, we really feel that it keep improving his work!! If you love the genre, aliens, spaceship fight and good writing that make it all look real than I strongly recommend this book!!
