Here's my take on guessing..
liam is definitely the prince.. liam is from the future how? we don't know yet.
cordelia maybe the kid from the princess and the knight.. And here comes the confusing part.. the author maybe the knight, the princess and the 'son' went to different place but the knight stayed behind for what reason we don't know.. and the knight (father) wrote their story and before the 'mother/princess' died she went back to the knight, remember where there is time gap between two places? my guess is the knight died first because of old age, remember when the prince liam said the place (hut) looks clean? the mother cleaned it? but i think it's a different person who made the tombstone for the two, it could be prince liam from the future or cordelia from the future herself..
here comes my second guess, cordelia is the one who wrote the second part of the book.. i just had the feeling.
