It's been a while since I picked up a Sword Art Online light novel, but the striking cover featuring Kirito as a vampire pulled me right back in.

While the story didn't lean heavily into traditional vampire themes, it offered plenty of other interesting elements, including a kelpie, a tragic love story, and an intriguing setup for an upcoming duel.

The ending left me eager to see what happens next. Now comes the hard part: waiting for Reki Kawahara to release the next volume—hopefully in less than three years this time.

Hmm. The book of backtracking, and not just in floor number. Has some interesting things, but nothing truly stellar. An hour after finishing it, I can't even recall a particularly noteworthy thing done by Asuna alone.

It felt like a big lead up book to the next big arc of the series, it was such a long wait for this volume though so I wish there was more in it but I know he has multiple series going on. 😭

3 stars even though this felt like fluff almost. After reading the afterword, it seems he needed to flesh out elven culture some, which makes sense. I am extremely biased because I love SAO, so I always rate these books high as I will take any bit of their journey before the 70th floor that I can. But I feel like until part two comes out, this arc feels a little hollow.
