Exclusive Cover Reveal: Clock Hands by Marieke Nijkamp and Sylvia Bi

Today on the site I am utterly delighted to be revealing the cover of Clock Hands by Marieke Nijkamp and Sylvia Bi, a middle grade graphic novel with a nonbinary protagonist releasing April 21, 2026 from Greenwillow Books/HarperCollins! Clock Hands is a companion to Ink Girls, but can be read entirely on its own. Here’s the story:

Raising your voice can change everything.

Vale has always dreamed of being a metalworker’s apprentice. But in Siannerra, the guilds rule with an iron fist, and their apprenticeship fees are impossibly high. So Vale and their guildless family must make do with the pennies and scraps they’re able to cobble together from work on the docks or in the market.

Until Maestro Giuseppi arrives from abroad, determined to build the city’s first astronomical clock. He doesn’t care for fees or exclusionary practices—and he sees Vale’s talent. He invites Vale into his workshop, and for a while Vale believes all their dreams are coming true. But everything in Siannerra belongs to the guilds, and if anyone tries to break free, there are consequences. Sometimes the gravest of consequences. Still, Vale refuses to stop dreaming. Or fighting. With the help of their friends, they plan to take on the might of the guilds. And together, they may just be strong enough to bend iron to their will.

A stand-alone companion to the acclaimed Ink Girls.

And here’s the fabulous cover, illustrated by Sylvia Bi and designed by Sylvie Le Floc’h!

Illustrated cover of CLOCK HANDS, featuring three tweens on the edge of a brightly lit clockface over a darkened Renaissance-like town. The tweens all wear practical, medieval looking clothes. The boy on the left--Caliste--has brown hair, brown skin, and wearing a laced up shirt. He's sitting down with one knee pulled up. Vale, in the middle, has black hair and brown skin. They're standing, dreamily looking out over the city. They're wearing a blue tunic, patched up pants, and a necklace. They have a slight scar on their chin. And to the right is Stella, who wears her red hair in a braid with a headband. She has freckled white skin, and she's wearing a pink and green dress. She's standing next to Vale and has her hand on their shoulder. She's smiling.
