Sword is the second book to Realm Lovejoy's Le Fay series, occurring shortly after Arthur's Round in Camelot reveals the Maven. When I compare the sequel to Henge, I'm not a huge fan of Sword – the book has a few good parts and bad parts that causes me to favor the first book over the second book.
Lovejoy first captivated me into the series with her modernization of Arthurian folklore – Camelot is integrated within the real world with technology and just comes across in the novel as something completely normal and acceptable by the rest of the world. Sword, however, doesn't really introduce us to anything new world-wise aside from a few new places within Camelot (dungeons are cool?) and Avalon.
Just like in the first book, Morgan is an ambitious person who will do anything to try and reach her goals. Much grief and questioning ensues when she doesn't get what she wants, but she ultimately decides it's not exactly the end of the world if she isn't chosen as Arthur's Maven as her visions determined. Morgan decides to take action into her own hands when she discovers that Arthur might potentially be in danger from a group called The Luminaries, who are trying to look for her for some reason. Everyone else chooses not to believe her or take her words into consideration and assume she's a little crazy in the head primarily because she didn't get the honor of being Maven.
In all honesty, just an injection of pity party for Morgan. But I like her good intentions, so I'm going to stick around and see if she becomes more batzy crazy sometime in the next few books. However, in the case of discovering something a lot more about Morgan's past, not much will be revealed, and anything revealed continues to shroud Morgan in a mystery.
Overall, Sword feels more like a bridge between the first and third book in the series – not exactly a novella, not exactly a progression either. But not having Sword between the two books wouldn't work either because the book unveils a few new plot twists towards the end that will leave readers interested in following the series into the third book and possibly beyond.
