The Shifters came to our world, hungry and desperate. Even with G1 being hot on their tracks, the alien forces continue their plans to control and dominate the world. Not to gain power and control...but to feed themselves...humans! In the third installment of Shifter+, the G1 team is coming together with a plan.

March has regained his memories and Higgins is coming out of her sense of defeat and loss. But unless they can get a firm grip on the invasion, the world will soon be plunged into a nightmare that dwarfs anything ever experienced! Plus... An extra G1 adventure mystery takes the team to a lost island in the Pacific, where experiments have gone wrong and prior agents are missing. What they discover is going to make HIggins feel like a doll in a monster's hand, when a giant experiment discovers her!
