I read this book at a very busy time of my life, when I had only about haft of a month to finish my MS degree of Chemistry (something related to “water”:) No regret at all about spending 1 day to finish reading! Love it, love the characters, love the elephant 
And, the book became an excellent bedtime story for my husband, who doesn’t like (and doesn’t have time) to read novels at all
