Typography

I bought a book for my son for Easter. The book is on Dinosaurs--his favorite subject. The illustrations are colorful and vibrant. The text seems well-written. However, the typography bothers me. Whenever a word is boldfaced for emphasis, the type changes from a serif type to a Courier-like type. Also, the kerning is off, which makes the words really jammed together and a little hard to read (see page on T-rex, line 3, boldfaced Tyrannoasaurus). This problem occurs on every page. I'm sorry the scan is a little hard to read--the pages of the book are quite shiny. Perhaps, I should contact the publisher and offer my editing/design services!
