Sorcery of Thorns starts with an interesting idea that made me curious and involved: a library like a prison of Necronomicon-like books, bound in flesh, partly alive, trying to manipulate people in various ways, fighting amongst each other, destroying minds and bodies of unguarded people and able to transform into murderous demonic beasts when damaged.
Then, almost immediately, Margaret Rogerson turns away from that premise and proceeds to write a very young adult fantasy romance where a Mary Sue orphan girl who has lived all her life in one of these libraries leaves it and falls in love with a young very eligible sorcerer while battling an old sorcerer in authority and patriarchy in general. Gad!
The writing is not bad, but nothing spectacular either. It's the way the author fails to put her character in even the slightest challenge that makes this book average at most. Whenever something bad happens, or rather about to happen, she immediately finds a new ability or a new friend to save her. Her "best friend" is there just to be used in various occasions and then forgot for the rest of the book. Men dismiss her opinions, not because she is a shut-in orphan and poor and uneducated and doesn't know anything, but because she is a woman. Only then to do 360s and completely believe and support her when the actual need arises.
And that ending! There is one thing that feels like a consequence, like it all wasn't some sort of bed game to spice up Elisabeth's romance, then it goes poof!
In conclusion I can't recommend this book. It's not bad, but certainly not good. Somehow I got duped again by the legions of horny girls using fantasy to scratch their itch and then rating books in droves. The only good thing I can say about the book is that it's standalone and not part of some misbegotten series.
