Into a Dark Realm is a readable fantasy book and you may either love or hate it depending on how you feel about Feist's Midkemia books.
I liked this book, but I have to say that it's not the best Midkemia book. Whenever I've read a new Midkemia book, I've had high expectations that Feist would finally come up with something as good and entertaining as Magician or Silverthorn, but he never does.
If you're a fan of Raymond E. Feist and like his fantasy books, you'll probably find this book interesting.
