“Ghosts Are Good” and so is this book.
The main character of Ghost King is Kasper Kloven, a lonely and bullied teenage ghost-hunter who dies and wakes up as a ghost and becomes the King of the Boggle, a ghost kingdom. He soon learns he must complete three trials to prove himself worthy of being king to all ghosts. Along the way, he meets a number of different characters and gains the approval of various ghost factions.
Ghost King explores many interesting themes. First and foremost, it’s the story of an underdog kid who comes out on top by trying his best, being himself, and gathering the support of people (or ghosts) around him. Kasper overcomes his trials by just being himself, and not bending under the pressure of expectations. The book also explores coping; for example, with death, with the expectations of others, with anger, and with struggles in a new, confusing world. Ultimately Ghost King is about following your heart and being true to yourself. We see a protagonist who undergoes great change: from a lonely, obsessive, and downtrodden kid to a confident king surrounded by loved ones.
I personally enjoyed the story for several reasons. Kasper was a relatable character as someone who has gone through "trials" and learned about themself, and the relationship between Oliver and Kasper was adorable. The plot was interesting and well-written. It was attention-grabbing, but still made me feel comfortable--there were struggles but they were dealt with positively, and it was not over the top with angst. The dialogue felt natural, and not awkward. The ghost world was cool and interesting, easy to engage imagination and picture what things would look like. The story is a manageable size and could be read over a weekend or two.
There are a few things that could be improved. There are a couple of grammar and spelling issues that pulled me out of the story a bit. There are some issues with world-building, as it wasn't always clear why things were happening. For example, why was the most important ghost event of 1,000 years centered around the main character's hometown?
Overall though, it’s a quite good book; something to read on weekend afternoons.
