What a fantastic new junior chapter book series for […] kids! Main characters Pou and Pipi are funny, clever and brave.


A satirical commentary on social media influencer culture in River Monster may go over the heads of younger readers, but it’s delightful for any adults consuming these stories too. The crackling dialogue throughout makes these books feel best suited for reading aloud.
