"If I ask you to buy a book, could you do it today?" This is the message Juan sent to Laia Santís (@vidaentrelibros) when they met again on social media, a few years after meeting at a concert in the heart of Vilafranca. Santís answered with a resounding yes and ran to the bookstore in search of his first suggestion: Ice Brother, by Alicia Kopf (La Otra Editorial). For four months, everyone in her house read the same pages of the same book at the same time and then discussed them.
