Review 1: The Doomsday Key audiobook by Bob

I wasn’t sure what I was going to get into with this one and was pleasantly surprised. For a story based on pre-history up to the present it was really interesting and suspensful. This may not be for everyone but I enjoyed it. I mainly prefer espionage novels but would like to see-hear more of this.

Review 2: The Doomsday Key audiobook by Kimberly Riggs Ruiz

I’ve been following this author for the last few years. I like his current events tie-ins, quick paced action, and fun characters. Reading his books reminds me of some of my first adventures in reading as a child with the Hardy Boys and Nancy Drew book; a cliff hanger ending in every chapter. If you like over the top adventure, suspense, and diabolical enemies this is the book for you.

Review 3: The Doomsday Key audiobook by Helen

Like Indiana Jones these stories are a romp on the wildside with great characters doing incredible things…yet through character development and a fast paced storyline you believe in their adventures…and are always routing for the good guy. The weaving of religion, science, technology, history and friendship is always a fine creation by Rollins and Doomsday Key is no different. Narrator was spot on and made the book come alive!

Although Rollins books don’t have to be read in order it is beneficial to read them in order because you understand the characters and their sub plots. This series focuses on a secret goverment team called the Sigma Force. Each book describes a different “mission” they are enlisted in. The books cover a short period of time…like 48 to 72 hours of the mission which usually takes place in several locations. The next book can be 6 months or a year later. It is a fun and energetic read!
