The Cryptid Keeper by Lija Fisher

(The Cryptid Duology, 2)
Life has gotten complicated for thirteen-year-old Clivo Wren. After taking up his deceased father’s mission to find the extraordinary creature whose blood grants everlasting life, Clivo is spending his summer not at camp or hanging out with his friends, but jetting all over the world tracking cryptids―while keeping his aunt Pearl in the dark about his dangerous adventures. At the same time, a shocking development unveils the truth about Clivo’s enemies, and the cryptids themselves are posing trouble at every turn. With the help of his crew of Myth Blasters, Clivo is going to need all of the tools, gadgets, and training he has to prevent the immortal cryptid from falling into the wrong hands―and to keep Aunt Pearl off the case.
