So I have Poison Study, Magic Study, and Fire Study sitting on my bookshelf and I thought that was it BUT it's not?? However, the information I've found is very vague and doesn't really explain very well which books belong to what and whether this actually is a trilogy or not (I see conflicting information) Also if it isn't a trilogy where can I find ALL the books in the series in the same editions? Any help or advice would be much appreciated (Also no spoilers, I've only read the first book!)
