This book has the least The Force Awakens spoilers of any I've read so far. Except for a detailed scematic of Kylo Ren's shuttle and a new Star Destoyer, the rest of this book gives us detailed schematics of ships from across the 6 films.
There are also many ships from The Clone Wars television show. Along with my favorite X-Wing and Y wing ships.
I learned a lot about the design and function of the ships. There is also some great information here for trivia games.
A great addition to any Star Wars fans bookshelf.
