Read this series if you are interested in 'going on an adventure'. It's certainly very imaginative, and fun to go through, but occasionally, it stated wrong facts. In other words, it may not be the best book for you if you are trying to find one that is fantasy, yet very educational.
I started it because I'm a total bird fan and wanted to read a story that is enjoyable and contains some accurate information on birds. (Of course, I wasn't expecting it to be like a non-fiction book, because 'The Journey' is a fantasy story.) The first book was good, and it gripped me straight away. However, when I got onto the second, which is 'The Journey', (I read a translated version, but I think it was translated fairly well.), I was distrubed by some inaccuracies. Firstly, crows (I like crows, raven etc. a lot.) were said to be simple minded birds, but of course, everyone who has some knowledge on birds know that they are some of the most intellegent ones. Also, on one page, I noticed a mention of an owl character having teeth. (Birds don't have teeth, and I really hope that was a translation error.)The story itself was fairly good, but unfortunatly inferior in many ways to other, similar novels such as 'Ratha's Creature'. (It's, in my point of view, the best book of its kind, better than the Warrior series but somehow not popular.)The third book of the series, which I began soon after reading 'The Journey', also contained a minor inaccuracy. It said seagulls never 'yarp' (vomit out) pellets at all, which is not true.
The rating I gave above is only my opinion (I was very annoyed by the fact crows were written as rather dull birds, but it's just me.). Try the book, perhaps you'll like it :)
