In an "Invasion of the Body-Snatchers"-style story, Meyer takes you on an adventure of survival, danger, and desperation as you follow Wanderer and Melanie- two minds sharing one body. The story is well-told, sometimes slow, yet always compelling. I found myself holding my breath many times throughout the book, waiting to see if they would be captured. Meyer does an excellent job of making the reader feel the emotions of the characters. The issues of ethics, trust, loyalty, and what is right are explored. I liked this book overall in spite of the feeling I got that it was a patchwork of dozens of other science fiction plots I have read or watched over the last 20 years. What the story lacks in originality, it more than makes up for in feeling and suspense. Like the Twilight books, The Host is fluffy brain-candy entertainment, but very enjoyable. With uplifting themes and a cast of characters who all fight for what they believe is right, this book is undeniably Something More Substantial.
