This beautifully illustrated biography of Edwin Hubble explores the curiosity that he possessed from a young age, and the many questions that he asked about our universe. This book invites children to ponder these questions as well: how many stars are in the sky? How did the universe begin? Where did it come from?

Isabelle Marinov speaks four languages fluently, but for a reason that defies her, English is her preferred language for prose. She likes to write across genres and has always been fascinated by physics and astronomy, but since her brain wasn’t wired for those, she studied law instead. The Boy Whose Head Was Filled With Stars marks Isabelle’s picture book debut. You can visit her at www.isabellemarinov.com and follow her on Instagram @isabelle.marinov.

Deborah Marcero is the author and illustrator of In A Jar (Putnam) and My Heart Is A Compass (LBYR). Deborah has always loved photographing starry night skies, but by painting the stars through the discoveries of Edwin Hubble, the universe became much more vast than it was before for her, too.
