The Undetectables

The tagline intrigued me, the story lived up to the interest. 
I enjoyed the mystery storyline a lot, I would love for this to be a series. 
I really liked the chronic illness rep and the understandable frustration for Mallory figuring out how to live with that and how to admit/ask for/accept help, as well as the main trio's friendship recovering and growing strong enough to help. 
The magic background was fairly well written though confusing that they'd not think of little things like making a chair more comfortable? Though it provided more funny lines, so not really a problem.
