Triton's Call: TetraSphere, Book 2

When Jewel Adams is abducted and taken to a place that most people don’t know exists, her friends are frantic to find her. The one alien race they thought they could count on refuses to help them. The other, the reptilians, are holding her captive. Will they harm her? Together, the four have abilities that, when combined, can save Earth from self-destruction, but they can’t do it without Jewel. In this exciting sequel to Terra’s Call, the four teens discover that things are not at all as they seem. There are more mysteries in this world than any of them have dreamed of, and they’re about to meet some of those mysteries head-on.
