[Full disclosure: I know Jim Hines personally.]
Libriomancer starts off Jim Hines’ third series. The first series – Goblin (or Jig) books – are comedies set in a fantasy world. The second series – the Princess novels – are fantasy stories with comedic elements. This series – Magic Ex Libris – is set in the modern day, but perfectly balances the tonal difference between the first two series. This book is just fun, with laugh-out-loud moments, but also shows off the skills that Jim has developed while writing the Princess series. That alone would be enough to make this book a highly recommended pick of mine.
But when you add in that magic comes from books, giving Jim an excuse to throw in all sorts of fun references? Why, that’s a delightful icing on the cake.
