Seeing as how I'm a Zombie Fiction fan and I had several plane rides coming up, I bought the first book, and promptly finished it in about 4.5hrs (according to my Kindle, I read faster than most), I then proceeded to buy all the rest of the books in the series.
In order, the books are -
"Under A Graveyard Sky"
"To Sail A Darkling Sea"
"Islands of Rage and Hope"
"Strands of Sorrow"
So, what'd I think? Well, for entertainment, it's fantastic! The whole series takes a very different approach to a world wide zombie apocalypse, and at least as far as the first three books go, they're good ol' frolicking sea yarns. That's as far as I'm going to go, I don't want to spoil it for you.
The characters grab you very quickly and make you root for them. While I disagree with Mr. Ringo's decision to make two of the main protagonists teenage girls (15 and 13 respectively), they're likable characters and it's interesting watching them grow up in the new apocalyptic world.
I was surprised that there were a lot of life lessons, and also leadership lessons in these books. It was obvious that Mr. Ringo had some good input from military members while writing the parts of the books involving military hardware, mannerisms, ranks, interactions etc. Some of the scenes where a USMC Gunnery Sergeant is ripping into some jr enlisted had me laughing my ass off.
The kindle versions had hardly any typos and I didn't notice any grammatical errors, which is refreshing after struggling through other kindle only zombie fiction.
These are honestly the first books by John Ringo I've ever read, and I will be looking at some of his others based on the quality of the writing.
Bottom line, I HIGHLY recommend these books. A refreshing change of scenery from most Zombie books, great characters, and VERY entertaining! Read 'em!
