Endgame is the final book in Gabrielle Lord's Black Ops trilogy taking Cal and his friends on another fast-paced, action-packed rollercoaster ride across the world. After so many adventures the teenagers break out from Shadow Island, escape a volcanic eruption, dodge a massive shark attack, finally arriving home for a short term rest. At SI6 Headquarters the team meet to discuss an extremely evil plan devised by Dr. Damien Thoroughgood. He is the megalomaniac who seeks power and domination over everyone else - utilising new robotic inventions and the Mordred key computer virus to achieve his goals. Cal is forced to under-take a criminal mission to save his kidnapped twin. Once again the clock is ticking down and Cal is running out of time.
The novel is set out in a diary format with the page numbers reversed counting down until the Damien's plans are carried out by the mudbots injecting the computer virus and causing monumental havoc. Gabrielle Lord's tech-savvy inventions, biological weapons and robotic monsters add drama and danger to the journey of the team. The lenticulated 3D cover is a great lead in to the novel.
Lord's loyal readership will be saddened to learn that this is the last novel in Cal's adventures according to the author's website. This is a great climax to Cal and his friends' adventures and is a highly recommended read for 12-15 year olds.
