I dont know what to say but "Please explain why you're giving this rating. Do not attempt to bypassing minimum character limits. A review is required."
The best book api I found !, Very simple to use, I am someone new to all this programming, but the wiki is very well done and gives you many examples to understand, and also the devs responded very quickly to my questions! , 10/10 ^^
