Cousins Otto and Sheed Alston are in a race against time—against stopped time that is. When a being called Mr. Flux freezes time in their town, the duo, with help from a mysterious man called TimeStar, who seems to know a lot about them, sets out to save the day. While beasts called Time Sucks threaten to destroy everything in their path, Clock Watchers, personifications of various times of day (e.g., Bedtime, Quitting Time, Golden Hour, A.M. and P.M.), are gradually aligning themselves on the side of good (the boys) or evil (Mr. Flux). Otto is methodical; Sheed full of heart; they are sometimes at odds with each other, and, from Otto’s perspective, definitely at odds with the Ellison twins, Wiki and Leen, sisters who have been stiff competition when it comes to past heroics, for which all four are known. While the cousins dive into the past to unravel the origins of Mr. Flux, the sisters work out the mechanics of battling the threat in the present. Fast-paced and funny, there is plenty of verbal sparring in the relationship between the boys and among the four, who are Black, but also plenty of warmth in this clever adventure tale. (Ages 8–11)

"The Last Last-Day-of-Summer reminds me that all children deserve to exist in magical spaces where their imaginations and familial bonds will them into heroism. Every single child should have the freedom to be one of The Legendary Alstons. And I, for one, am grateful to Giles, and this brilliant story, for that reminder." --Jason Reynolds, author of Newbery Honoree Long Way Down

"The legendary heroes of this legendary book are already legendary when the story begins From there things can only get legendary-er " --Tom Angleberger, author of the Origami Yoda series

"Lamar Giles has written an instant classic--readers won't want their time with the Legendary Alston Boys of Logan County to end." --Gwenda Bond, author of the Lois Lane series
The Hardy Boys meets The Phantom Tollbooth, in the new century When two adventurous cousins accidentally extend the last day of summer by freezing time, they find the secrets hidden between the unmoving seconds, minutes, and hours are not the endless fun they expected.

Otto and Sheed are the local sleuths in their zany Virginia town, masters of unraveling mischief using their unmatched powers of deduction. And as the summer winds down and the first day of school looms, the boys are craving just a little bit more time for fun, even as they bicker over what kind of fun they want to have. That is, until a mysterious man appears with a camera that literally freezes time. Now, with the help of some very strange people and even stranger creatures, Otto and Sheed will have to put aside their differences to save their town--and each other--before time stops for good.
