Shadow Zone

Shadow Zone by Iris and Roy Johansen is the sequel to their book Silent Thunder.

Hannah Bryson is a submarine engineer. She has been creating subs for years now and has the opportunity to test her latest mini sub in the waters above Marinth - an underwater city that was recently discovered by her friend Melis.

The only large piece about the city of Marinth that is missing is how the city died out. Its ultimate destruction was a tsunami that put it under water but the dying of the people who lived there started long before the giant wave struck the island.

When Hannah finds a trellis that explains the end the city, she uses her sub to bring it to the surface. But Melis and Hannah are not the only people interested in something that could erase the life from a city. When the trellis is stolen on its way to the lab, Hannah calls on the only person she knows who is capable of dealing with any situation.

Together Hannah and Nicolas Kirov hunt down the trellis. The search will take them all over the world and to the edges of death in an attempt to stop an arms dealer from using the knowledge to create a substance that will kill all life in the oceans.

The Johansens have teamed up to write fast-paced thrillers that will have readers staying up late to find out what happens next. Shadow Zone is no exception.
