Many writers have a daunting task ahead of them to produce a sequel to a complex and involved first novel, especially one as intriguing as The Lost Theory. Michael Kelley has risen to the occasion with an equally compelling thriller that finds new and exciting ways to raise the stakes and push the development of established characters in different directions. […] The Devil’s Calling is an excellent example of an action thriller that balances high stake encounters with a thoroughly human grounding, thanks to its balanced protagonists and excellent prose.
