11. Harry Potter and the Deathly Hallows (last book in series)
"Readers beware. The brilliant, breathtaking conclusion to J.K. Rowling's spellbinding series is not for the faint of heart--such revelations, battles, and betrayals await in Harry Potter and the Deathly Hallows that no fan will make it to the end unscathed. Luckily, Rowling has prepped loyal readers for the end of her series by doling out increasingly dark and dangerous tales of magic and mystery, shot through with lessons about honor and contempt, love and loss, and right and wrong. Fear not, you will find no spoilers in our review--to tell the plot would ruin the journey, and Harry Potter and the Deathly Hallows is an odyssey the likes of which Rowling's fans have not yet seen, and are not likely to forget. But we would be remiss if we did not offer one small suggestion before you embark on your final adventure with Harry--bring plenty of tissues."
