I do not read Polar, beginner in this kind I started this book, and it's a surprise for me, I like! So Dare polar and start with this one! Reviews all specialized sites are excellent, and devours the book very quickly. For cons, I was hesitant to put only 4 stars because there was a problem ... no result yet published, then we would immediately start the next, it's pretty frustrating. But one can forgive this expectation, if it does not last too long, so we are attached to Nils.
