Series: Codename Omega, #3
Published by Lulu Publishing Services on March 29th 2017
Those who oppose Grey’s Tower tend to end up missing or dead. Jenny’s friend Matt vanished while trying to uncover the Tower’s secrets. Jenny has promised to discover what happened to him, and she must keep those she loves from facing the same fate.
Meanwhile there is another threat looming. An alien spaceship is heading for Earth. Jenny and her allies must find a way to stop it but there may be another danger nearer to hand. Someone close to Jenny is keeping secrets – secrets that might hold the key to the spaceship’s mission, to Matt’s disappearance, and to what their enemies have planned.
I wasn’t as crazy about Hidden in the Signal as I was about Omega Rising and Traitor in the Tower. Jenny is on the search for Matt and an alien spaceship is headed for Earth. The story was a little all over the place and I never quite felt like I knew what was going on. I think trying to have two separate story lines running at the same time was a bit of a problem for such a short story (120 pages according to my Nook app).
Still a fun ride, but less so than the previous two books.
