Great as a box set

I am not sure if this story is worth it without the box set, but as it is, I feel it was at the very least a great time killer.
The story starts slow, but gets more interesting towards the end with more varied powers. Used it to kill time while cleaning or driving. Worth the 1 Credit. If you get attached to series, be aware that this one has quite a few books even after the box set.

Lets hope we get a box set for 4-6 and 7-9 too! ?
