Anyways, I thought it was surprisingly good. The beginning was alright, but I like the idea of using Spanish origins instead of Latin.
By the way, DON'T DIE HUMBERTOOOO! Although, any name starting with "Hum..." makes me think of Humpty Dumpty. The characters have a lot of depth, and the main character was really likable. Which probably had to do with the fact that she wasn't "stunningly beautiful" or even pseudo-beautiful (when characters find themselves ugly but others think they're gorgeous), at least for the majority of the book. Although the romance part... it's a bit of a mystery to me as to why Humberto falls for Elisa so easily; maybe he was impressed by her inner will and wit? Eh.
Also, I could have used a map... the locations left me a bit confused. Usually I don't use maps, but it could have helped. And the world-building was pretty lacking... who are the Inviernes? Do they live in some pre-Pevensie deprived land and seek to escape Jadis? Not to mention that controlling the Godstone through prayer was disappointing.
