Catalyst by Lydia Kang
In the past year Zel lost her father, the boy she loves, her safety, and any future she might have imagined for herself. Now she, her sister, and the band of genetic outcasts they’ve come to call their family are forced on the run when their safe house is attacked by men with neural guns. But on the way to a rumored haven in Chicago, Zel hears something–a whisper from Cy, the boy who traded himself for her sister’s safety. And when she veers off plan in order to search for him, what she finds is not what she expected. There’s more to their genetic mutations than they ever imagined…aspects that make them wonder if they might be accepted by the outside world after all.
When the authorities come knocking at the door, Zel and her companions must flee their home. Zel goes after Cy and decides to meet up with the rest of her friends in Chicago. However, after finding Cy, nothing else goes by the plan.
Catalyst is the sequel and conclusion to last year’s Control. Part medical thriller, part scifi adventure – this story is completely thrilling. The characters are engaging and the story is full of heart-pounding suspense and drama. I’m glad not every series needs to either be a trilogy or seemingly endless. This duology was just the right length. I enjoyed first installment, and the conclusion was just as gripping – and satisfying as well. I look forward to more from this talented author.
