This is very easy to read. Probably the most accessible book by Dostoevsky that I have come across thus far, so a good way into his works I think.
The text is well-paced, with a good narrative and clear character structure (always one of his strengths). The storyline is interesting, with the central character encountering dark desires that seem to take him to the brink of disaster, and his companions around him also heading towards impending doom and catastrophe - there really is no time to breathe while reading this!
Dostoevsky weaves his magic by making each character have a secret side that you can only glimpse at, thereby creating the desire for the reader to want to find out more about everyone, and get to the heart of matters. A true master at work.
My one small criticism would be that although Dostoevsky finishes the book well, I felt it ended a shade early, it seemed to be somewhat unfinished to me. He was under a lot of pressure to complete this novel, and perhaps it shows near the end.
All in all, a great book though.
