Move over Twilight and your vegetarian vampires. Summer just got a whole lot more interesting. You would think that by book six of the PLL series, author Sara Shepard would have lost steam. But oh no. The delicious mystery continues and a rapid-fire pace. Everything you think you know always turns out to be wrong, and you are forced to reevaluate everything. Paranoia reigns supreme as you wonder who is telling the truth, who is bending the truth, and who is simply keeping quiet. Can we even trust these girls when they share their stories with us as readers? Can the girls trust their own memories and understandings?

Do we even know who is alive or dead any more?

Killer puts everyone on trial, and Shepard masterfully weaves a yarn that gets more and more tangled the more you read.

Moving back and forth between past and present and between the points of view of each of the girls, Killer revolves around the annual school tradition of the flag for the time capsule. Each year, a flag is cut apart, and pieces are hidden around the Rosewood community. Students must follow clues to find the flag pieces, and victors decorate their piece which will go in the time capsule, making them legends in Rosewood Day history.

Before Ali disappeared, she had captured part of the flag, but then her piece was stolen. Who stole it? Where is the piece now? How the heck will this reveal anything about the greater mystery of Ali and the notoriously creepy and awful A?

Rich with detail, the story of the pieces of the flag echo the puzzle pieces of the mystery coming together.

Simply delightful.
