Piranha has all the usual Dale Brown ingredients of high tech weaponry, battle situations, interpersonal tensions, and thankfully for this type of book, remarkably little gratuitous bad language. The body of the book is the usual buid up of the story components, and I found that part to be enjoyable, and compelling (5 stars for this), but then the climax came and went and I was left thinking "did the end really support all the build up?" - for me it didn't (1 star for this).
I realise that in my reading of Dale Brown's books this feeling of disappointment at the end has emerged only recently, but has been a consistent pattern. I also note that the last three I have read have all been jointly written by Dale Brown and Jim DeFelice. I don't quite know how two people write a novel, but I wonder if this shared ownership has anything to do with what seems to me to be a shift downwards in the quality of Dale Brown's novels?
