I'd only read one of these before and while two were set in modern times, one even set for definate in this world they were still good. I liked them! 
 I think my favourite was Lost. 
 I also liked the one of the Tree that became a man and how the next one linked to it. Though I would have liked to have known what happened when they met with Numair...;p 
 And I have always liked Student of Ostriches, I like to know the beginnings of Legends.
