It is unusual to have a Star Trek book like this, instead of focusing on the Federation the author has chosen to write about the Klingons and it works. The characterisation is mainly based below the decks, whch gives an interesting edge to the book.
I find the desciptions of the lower ranks brilliant, especially the banter between the troops. I did laugh out loud. Sometimes the Klingon Empire is displayed as being too one-dimentional but the characters are brave, cowrdly, thick, funny and grumpy. I found the love story between the Chief Engineer and Leskit to be pure genius. I have alll the books of this series and cannot wait for more
Decandido is one of the best Trek writers and he has created a franchise that is story teling at its best. Give him a go, you won't regret it.
