Idan Ben-Barak has written several books so far, including Do Not Lick This Book and Small Wonders: How Microbes Rule Our World; they’ve been translated into over a dozen languages and won a couple of awards. He lives in a smallish apartment in Melbourne, Australia with his wife and their two boys. Sometimes, after they go to bed, he grabs the guitar and makes up harmless little tunes. He has degrees in microbiology and in the history and philosophy of science, a diploma in library studies, and a day job that has very little to do with any of the above. You can find Idan on Facebook (too often for his own good), Instagram (occasionally) and Twitter (rarely). When he has anything to say about writing he says it on his blog.

Frost also illustrated Ben-Barak's Do Not Lick This Book.
