In this page-turning middle grade series by New York Times bestseller Margaret Peterson Haddix, Colin and Nevaeh, whose parents own rival junk-removal businesses, uncover mysteries hidden in attics and basements and discover how trash can become treasure. In The Secret Letters, Colin and Nevaeh find vintage letters that lead to interlocking mysteries from the 1970s and '80s, and they learn about "women's lib," the ERA, and other social issues from that time in history--and the way echoes from that era affect Colin and Nevaeh themselves. When Colin finds a shoebox full of letters hidden in a stranger's attic, he knows he's supposed to throw them away. That's his summer job, getting rid of junk. But Colin wants to rescue the letters--and find out what really happened to best friends Rosemary and Toby way back in the 1970s. Meanwhile, across town, Nevaeh also finds a mysterious letter. But this one reads like a confession to a crime. And Nevaeh knows her father, the "Junk King," expects her to join the rest of the family in blaming a single suspect: his business rival, Colin's mom. But that's not what Nevaeh wants, either. Even as one set of letters bring Colin and Nevaeh together, the one Nevaeh found threatens to tear them apart. Is their new friendship as doomed as Rosemary and Toby's? Each book in the Mysteries of Trash and Treasure series will examine a different time period in history and make readers think about how we value the stuff we hold on to--and what it is that makes it valuable.

The fire at the Triangle Waist Company in New York City, which claimed the lives of 146 young immigrant workers, is one of the worst disasters since the beginning of the Industrial Revolution, and the disaster, which brought attention to the labor movement in America, is part of the curriculum in classrooms throughout the country.
Told from alternating points of view, this historical novel draws upon the experiences of three very different young women: Bella, who has just emigrated from Italy and doesn't speak a word of English; Yetta, a Russian immigrant and crusader for labor rights; and Jane, the daughter of a wealthy businessman. Bella and Yetta work together at the Triangle Shirtwaist Factory under terrible conditions--their pay is docked for even the slightest mistake, the bosses turn the clocks back so closing time is delayed, and they are locked into the factory all day, only to be frisked before they leave at night to make sure they haven't stolen any shirtwaists. When the situation worsens, Yetta leads the factory's effort to strike, and she meets Jane on the picket line. Jane, who feels trapped by the limits of her own sheltered existence, joins a group of high-society women who have taken an interest in the strike as a way of supporting women's suffrage. Through a series of twists and turns, the three girls become fast friends--and all of them are in the Triangle Shirtwast Factory on March 25, 1911, the day of the fateful fire. In a novel that puts a human face on the tragedy, Margaret Peterson Haddix has created a sweeping, forceful tale that will have readers guessing until the last page who--if anyone--survives.
