Alexey Skobkin (books) reviewed A Certain Magical Index Vol. 1 by Kazuma Kamachi (A Certain Magical Index, #1)
Well... This is a bit better than an animated series...
3 stars
... in some parts, but I'm still reading this to reach other chapters where new characters are and non-magical part of this universe are being present. I didn't like this character pair of Toma and Index in the animated series and still can't get myself to like them in the light novel version. Maybe something will change in next volumes, but now I'm still waiting for other plot arcs.
