As previously mentioned, it’s another long one, a complete trilogy in one volume, so you will in essence be getting three books for your money to keep you busy until Part 2 comes out (possibly Christmas 2014 but no promises).
Don’t rush it! Take your time and enjoy it; it’s going to be a while until Part 2.
I am taking a short break, and then fulfilling my promise to return to Professor Diaries to complete the next installment in that series (#2). PD readers have been waiting patiently for a long time and I am long overdue.
