SOLVED. Fantasy/Book series: boy lives in an orphanage who is dyslexic, takes a test, travels to a home where he goes to another dimension/world along with a group of other children (where they undergo quests?). Spoiler ahead. [s]

The books I remeber had a green cover with some fancy text and a picture in the middle, while another had a yellow cover and another had a maroon (or brown?) cover.

Books where read in 2011-2012

Do you remember what reading level this was for?

This reminds me a little of The False Prince by Jennifer Nielsen. It's probably not correct but give it a look and see if it looks familiar.

The Serpents of Arakesh by V.M. Jones? There are different cover images.

Yes! Thank you for finding this for me!

Great. Glad you found your book series, Isabella.

I removed "...he finds out he is the prince." from the topic header and added a spoiler alert. (Spoilers are okay in the comments; we just need a clear warning.)
