Wolf Signs is a fantastic paranormal shifter book by Vivian Arend. Ms. Arend has given us a well-written book and filled it with awesome characters. Keil and Robyn's story is a fairly quick read, perfect for shifter fans with limited reading time. There is plenty of action, drama, suspense, humor and sexy bits to keep readers glued to this book. I enjoyed reading every single page of Wolf Signs and look forward to reading more from Vivian Arend in the future. Wolf Signs is book 1 of the Granite Lake Wolves Series but can easily be read as a standalone. This is a complete book, not a cliff-hanger.
