As I'm about to go to bed, Naughty Ninja Takes a Bath is the #1 children's book in the entire country on Amazon, in its first day. This is not so much an indicator that NN is destined to be a classic, but that Amazon First Reads is an effective marketing program.
But it's like if you beat the defending NCAA wrestling champ on a locked hands penalty point. You're not going to complain about it.
And so it is.
An excellent day.
