Mastermind

This is like a 3.5 because I enjoyed a lot about the book, was really satisfying to see Theo and Jessica working together after their respective series have ended. Except Jessica who is supposed to be a genius in her own right is nerfed and Theo does like all the thinking...So that was disappointing. Also another really anticlimactic ending..this author just does not know how to write them!! I really liked the character interactions though so not a terrible read, and I'll continue with the next one.
