As with every round of this readathon, you do not need to read mythology books, simply ones that fit the challenge prompts. However, I know some of you enjoy the extra challenge of using theme specific books into your TBR so I’ve found a few that you might be interested in. I’ve not read all of the books below, only some, so I can’t recommend which are most likely to suit you, but think of this as a starting place for your own research. Please do add any suggestions you come up with in the comments.
This is a mixed bag of Celtic mythology inspired reading — some are almost direct retellings of stories like Tam Lin (Scottish) or the Mabinogion (Welsh), while other are looser featuring creatures from Celtic folklore like kelpies and selkies. In fact, since the idea of ‘fair folk’, Sidhe and fairy deals feature heavily in Celtic folklore, you could probably use a lot of fantasy novels featuring the fae.
One element of Celtic mythology you won’t find here is Arthurian Legend. I felt that was a large and rather separate topic ( and hinthint might make for a Mythothon round all of its own).
Where a series would fit, I’ve listed the first book.
