Scored
Every adult life runs on numbers nobody ever taught you to read: a credit score that swings a hundred points over one late payment, an insurance premium built from a table that bets on how long you'll live, a resume filtered by software before a human ever opens it, an admissions formula that reduces a teenager to two components, a criminal-risk score that helps decide who goes home and who doesn't, and a feed that decides what you see next. Scored is the book that actually shows you the arithmetic behind all six — not a critique of algorithms, and not a graduate-level textbook, but a plain-language, fully worked walkthrough of the real formulas: the weighted sum, the logistic function, the actuarial equivalence principle, decile risk ranking, and recency-weighted decay. Following an ER nurse rebuilding her credit after a layoff and a small-business owner fighting a stale data error that auto-declined his loan, alongside real, documented cases — Amazon's scrapped AI recruiting tool, the UK's 2020 algorithmic grading scandal, and the real Wisconsin Supreme Court case that tested a criminal-risk algorithm's constitutionality — this book hands you the actual math, worked on real numbers, so you can approximate your own scores with a calculator and know exactly which levers move them. No hedging, no folklore, no black box. Just the formula, shown whole.

The Someday Letters
Eleven-year-old Junie Alvarez has a script she says whenever someone asks about her dad: he's working construction up north. It isn't true. Her father is serving eighteen months at Ridgeline Correctional Facility, and since moving in with her grandmother in the small coastal town of Cobalt Cove, Junie has gotten very good at the lie. Then she finds the Lantern House — a boarded-up lighthouse keeper's cottage on the bluff where, for over fifty years, kids in town have quietly left unsent letters to whoever they're missing. Someone has been reading them. Someone has even been writing back, signed only with the initials M.K. As Junie and two new friends — each carrying an absence of their own — chase down who the Keeper really is, Junie is also learning to carry the truth about her dad: the fifteen-minute monitored phone calls, the two-hour drive to a visiting room, and the fact that a person can be sorry and still have done something wrong, and that both of those things can be true of someone you love at the same time. The Someday Letters is a mystery with real heart, for the millions of kids who know exactly what it's like to have a parent who's "away" — and for every reader who has ever needed a place to put down something too heavy to carry alone.
