Grail of Stars

Rhianna's final task is to find the mythical Grail, which Arthur's knights never managed to bring back to Camelot. If she can take this powerful fourth Light into Avalon, where her father's body lies in the crystal caverns, then she hopes its magic will heal the king's mortal wound so that he can reclaim his throne from the dark knight Mordred. However, not even the Grail can rescue more than one soul from the dark, and when Prince Elphin goes missing Rhianna must make a heart-breaking choice that will decide the fate of both worlds. Book 4 of the enchanting Pendragon Legacy series by the award-winning author of 'Song Quest' "e;There is magic at work here as strong as Merlin's."e; Mary Hoffman, The Guardian.
