I remember really liking Legend, but the sequel is another thing. I don't know if it's because I read Legend a while ago, but I just found the writing in Prodigy extremely basic (especially in Day's perspective). This stopped me from delving any deeper into the world and story. Also I found that the plot twists were abrupt, just there to induce the readers attention for a few more chapters before another twist was inserted. On top of all that I'm not crazy for the love '', it just felt cheap, if they can be said for a book. 
 Of course there were a few things that I enjoyed, like the world building.
