Dark River by Erin Hunter (2008)

Once I opened up the second book of the third saga from hit authour Erin Hunter I couldn't put it down. This book is full of great action and adventure for the three Thunderclan apprentices Hollypaw, Jaypaw, and Lionpaw as they discover secrets that should create a forrbidden relationships and be helped by a mysteirious cat from the past. I definetly recomend this book to all cat lovers or just those who want a book series with a gripping plot line and adventure.
