Anna and Theo are two separate books by Amanda Prowse but each tells the story about what happens when two very different people fall in love with each other.
There are two sides to every story and each book tells Anna and Theo's own stories.
I thought this was an unusual concept, two books, one story, but each book telling Anna and Theo's own side to it. Each book could be read as a standalone story, however, some things from one book are explained in more detail in the other, so to get the full story you would need to read them both.
I actually enjoyed Theo more than Anna, I'm not sure why, it just seemed to grip me more than Anna did. I find Amanda Prowse books a bit hit and miss, some I love and some are just okay. I'd recommend Anna and Theo, I like the idea of two different sides of the story and I did enjoy each book but I wouldn't say they're her best.
