I really enjoyed reading this first installment. The ages are mentioned in the first portion however, no actual sexual acts until Horton comes of age.
There were a couple British terms new to me but, google did its usual fine job at definitions. The tempo was good in most spots. The author did a reasonably good job in crafting characters that you could relate to or sense their feelings, more so for the main character.
I'm looking forward to seeing the following segments in the series.
The edition I have did include a couple minor spelling, double word, and grammar issues but not so frequent that it distracted from the reading.
