Bestselling author Kathryn Lasky writes for the chapter-book set! The Deadlies are like any other family with a loving mother and bright, rambunctious children. Except they're spiders. Really, really poisonous ones. But Edith and her children are kind and cultured. In fact, the Deadlies had been happily living in a symphony hall until Edith's son, Felix, had a . . . misunderstanding with the maestro. Now they're on the hunt for a new home. That is, if they can outwit the overzealous arachnologists and evil exterminators on their tail. Will they ever find a place to live in peace?

Can the world's friendliest spiders spin a web strong enough to catch . . . a criminal? They're sweet and friendly . . . but they just happen to be super toxic. The Deadlies are the world's most misunderstood family of spiders. Kicked out of home after home, all the Deadlies want is to settle down in a cozy web with no exterminators around. Now they've found the perfect place - the Rare Books room at the Boston Library. The librarian isn't afraid of the Deadlies, and they have lots of lovely books to explore. But their peace is threatened when a thief starts targetting the library. Can the Deadlies spin a web big enough to catch a crook - or is it back on the road once more?
