While not as good as the first installment, it was still fun to be back with Malcolm and Owen in City Mouse. Malcolm and Owen are getting to know each other and realizing that their relationship isn't all fun and games.
The biggest issue I had was that the authors kept highlighting the fact that these characters are polar opposites which, IMO just highlighted the differences in their writing. This book was far less cohesive than the first.
I still enjoyed reading about Malcolm and Owen but if I wanted to re-visit them, I would be going back to County Mouse.
