Books 1~3 in this series: Apocalypse Dawn, Apocalypse Crucible, and apocalypse Burning were all well written, intriguing, well orchistrated works that told the story of soldiers, sailors, and people associated with the military that were left behind following the Rapture of the Church, and events immediately leading up to the Rapture. All of the books dealt with a fictitious war between Turkey and Syria, with the US Army's 75th Rangers and UN Peacekeeping forces caught in between.
The main characters, 1SGT Samuel Adams "Goose" Gander, Captain Cal Remginton, Megan Gander, Joey holder, Chaplain Delroy Harte, Danielle Vichenzo, and Jenny McGrath, are all well-developed characters throughout the novel series. They are shown as real people facing real problems, dealign with real doubts about God and Faith, and Jesus Christ. The settings for the novels are all real places, and the events surrounding each are easily stamped in one's memory. Books 1~3 do well in shaping these characters, telling the story of soldiers caught in between a rock and a hard place on the battlefield, and their dependents and loved ones in the States.
Unfortunately, Book #4: Apocalypse Unleashed, leaves the reader basically feeling empty at the end of the book. There are so many loose ends left untied, so many endings to the story that we are not told and few details left to give us any kind of hint at how this story will eventually end for each individual character. How do 1st Sgt. Gander and his Captain whittle out their eventual adversitiy to one another? What happenes to the CIA agent known as "Icarus"? How does Megan and Joey Gander end up their stories, and what happens with Jenny's Dad? Do 1st Sgt. Gander and Cpl. Hardin eventually bring an end and confrontation to their adversarial relationship? What, eventually, did Chaplain Harte do (his character was left dangling in Book #3)? What happend to his Daddy's reformed and renovated church? After he supposedly left to rejoin his ship, who toook over caring for the flock if and when, he ever comes back? And how does Nicholae Carpathia bring peace between Syria and Turkey? What fate does CIA Section chief Alexander Cody meet? What about reporter Danielle Vichenzo? Did or does she ever coem to faith as Megan Gander, 1st Sgt. Gander, and a few others do? What about Joey? How does his conflict with Zero, RayRay, Bones, Dropper, and Derrick come to fulfillment?
It is questions such as these that remain unasnwered and unfulfilled.
Apocalypse Unleshed feels and seems more like a book that Mr. Odom wrote just to write for writing's sake, not to fulfill any of the story lines he details in the first three books. Honestly, it would have been better for Mr. Odom to not have bothered to even write a 4th book after the end of Apocalypse Burning, as Apocalypse Unleashed was anything but "unleashed" (more like tame, lame, and stale to read at the end).
You want a piece of advice, expectant reader? From my point of view, I'd say don't bother. I'd almost say don't bother with the entire series due to how this book ends. Instead, read or re-read Neesa Hart's Political Left Behnd Series: the novels in that one -- "End of State", "Necessary Evils", and "Impeachable Offense" -- are far better written, and leave the reader excpecting a good book #4 (if there is to be one), and essentially leaves the reader fulfilled if a book #4 doesn't appear. Had Mr. Odom done the same with this series, it would have been better than the story he gave us and published with Apocalypse Unleashed.
To sum up: save your money. Stop with Book #3, and read or re-read Neesa Hart's series. Apocalypse Unleashed will leave you highly disappointed...
