Amazon is offering Mad Science Institute for free currently. It is regularly 14.99 and appears to be a kid/teen pleaser novel.
Sophia "Soap" Lazarcheck is a girl genius with a knack for making robots-and for making robots explode. After her talents earn her admission into a secretive university institute, she is swiftly drawn into a conspiracy more than a century in the making. Meanwhile and without her knowledge, her cousin Dean wages a two-fisted war of vengeance against a villainous genius and his unwashed minions.
Separately, the cousins must pit themselves against murderous thugs, experimental weaponry, lizard monsters, and a nefarious doomsday device. When their paths finally meet up, they will need to risk everything to prevent a mysterious technology from bringing civilization to a sudden and very messy end.
