Rhianna Pendragon is the secret child of King Arthur and Queen Guinevere, so secret that even she doesn't know who her parents are. She has been raised in the fairy realm of Avalon but has always dreamt of visiting the world of men. When Merlin arrives in Avalon with Arthur's body it looks like Rhianna will get her wish. Arthur was killed by his nephew Mordred but there is a chance he can be saved - if Rhianna can find the Sword of Light and bring it back to Avalon.
Rhianna sets out for the human realm to search for the sword with her friend Prince Elphin and their magical horses. They aren't the only ones searching for it though and Mordred is determined to do whatever it takes to stop them. He can't risk Rhianna taking control of the Knights of the round table and becoming accepted as King Arthur's heir. Mordred will stop at nothing to claim Camelot and it is up to Rhianna to make sure that doesn't happen.
Although I don't read many children's books I couldn't resist Sword of Light, I've always loved the legend of King Arthur so was looking forward to reading Katherine Roberts' take on it. It was great to see characters we already know and love alongside new ones like Rhianna. She is a strong heroine and I loved the friendship between her and Elphin. It's nice to see how much they care for each other and how they always stand together to fight.
Add in magical horses, knights and a dragon and you have a magical tale full of adventure that is hard to put down. This is the kind of story I would have absolutely loved as a child and still thoroughly enjoyed even as an adult. I'd definitely recommend Sword of Light and I'm looking forward to reading the next instalment of the Pendragon Legacy when it comes out later this year.
