I bet you cannot guess how it ends :).
Good but "the invader" by the same author, was better.
I do agree with Ella: the part of the story about Mrs. Carew and her search for her long lost nephew is very touching indeed. The ending of this book however is a bit predictable and disappointing. I did like the first half but the second half came off as unnecessary OR as something that needed to be a third, separate novel. In the end tho, I still will recommend this book for everyone who enjoyed Pollyanna book #1 and is curious about her fate. :)
This is a fun book about an imaginary city (or cities really) that come to life in another dimension. It is also a story about a duo of children that must step into this dimension and save that world. The book itself is kind of reminiscent of Narnia's Voyage of the Dawn Treader and probably helped inspire C.S. Lewis in his Chronicles of Narnia.
