A worthy spinoff of The Borrowed World. I was going to wait on this series, but when The Borrowed World book #9 heavily involved the happenings of The Mad Mick between Book 8 and 9 (I’ve already read 8), I stopped reading 9 and picked up on this instead. I want to catch up before going back to the original. Having read about The Mad Mick in Book 1 of Locker Nine, I felt as if I’m already familiar with his character. While some readers may be annoyed at how the different series interact with one another (and how dependent Book 9 of the Borrowed World is on The Mad Mick), I personally love it. This world is a big one and I enjoy every minute of it. All series included.
