Together in this one book are two of the Hardy Boys’ oldest mysteries that began the classic mystery series of the sleuthing siblings. In The Tower Treasure, the Hardy boys' summer is ruined by a red-haired robber striking all over town. No robbery is more devastating than of Tower Mansion, home to one of the wealthiest families around. To prove the mansion’s caretaker is innocent, the Hardy boys will have to solve the mystery of the stolen jewels before time runs out. In The House on the Cliff, Frank and Joe are asked to help out their famous private detective father on his latest drug smuggling case, which sends them to an old house on a cliff to serve as lookouts. But when cries for help lure the boys inside the house, they realize they could be in more danger than they thought.

The book focuses on individuals writing in the '90s, but also includes 12 classic authors (e.g., Mark Twain, Louisa May Alcott, J.R.R. Tolkien) who are still widely read by teens. It also covers some authors known primarily for adult literature (e.g., Stephen King) and some who write mainly for middle readers but are also popular among young adults (e.g., Betsy Byars). An affordable alternative to multivolume publications, this book makes a great collection development tool and resource for author studies. It will also help readers find other books by and about their favorite writers.
