Alone is a non-stop ride of pulse-pounding action. From the minute Bobby pulls the trigger up until the very last page, Alone will keep you guessing and turning pages. Gardner is also very skilled in portraying her characters in a lifelike fashion. None of them are truly heroes and none of them (except for Catherine's rapist) are truly bad guys. She gives us someone to root for, Bobby Dodge, and plenty of other characters to try to figure out. The most intriguing character is Catherine Gagnon, who Gardner never labels and leaves it up to the reader to make a decision on.Alone provides readers with an interesting and tricky plot and also gives them the perfect characters to play it all out. This book is recommended to anyone who enjoys thrillers or mysteries.
