Sixty-six million years ago, an asteroid hurtled through space toward an ancient Earth that looked very different from the one we know today. And in One Cosmic Rock: The Story of the Asteroid that Changed Our World by Karen Krossing we see how that came to be in poetic language for the picture book crowd.
Good for ages five and up, this book is a simple, but involved, non-fiction story that has interesting illustrations by Julia Vasileva. They are neither realistic or abstract, but a form of cartoon that has realism to it. They are not overlay colorful at times, but they are not lacking either. Details fit the scene and situation. Everything works out slowly, but steadily, across the pages. 
Filled with facts, things read more fiction. Sometimes things can be a smidgen bogged down, but overall it is open and works with the listener and/or reader. Read via an online reader, I am curious how things will look finished. I see either a smaller picture book, or a slightly larger than usual size. But that won’t be learned until mid to later February 2026 when it comes out. I was neither WOWED or underwhelmed by things. It is a cozy, nice book. 
Now comes the part where I say that I enjoyed the book, will be giving it as gifts and I am wondering about other things they have written. I have seen a few titles they have done and plan on looking at a few others, but I might not come back to this one. It is a nice read once for me. Maybe after time has passed (like when it comes out) I might do a second reading, but for now I’m more than good. However, I think it will work well in a classroom setting and for the kid who likes science, space, or a combo of the above.
