Great characters, main character “acts” like young college guy … appropriate for this story as he makes mistakes and learns from them. Love the various pets rescued/adopted along the way. Best earth v. alien takeover plot — Dr. Who had a couple of similiar episodes but this is much more indepth with realistic use of scifi/gamer action, including sound effects. Several VERY GOOD male and female readers make it easier to “recognize” characters. Will begin second book today! ?
