Cozy books exploring Catholic faith

I am looking for some cozy books exploring the Catholic faith that I can read before I fall asleep.

Perhaps some easy reads that explore Catholic concepts like intercession, the rosary, the value of saints in the church, sacraments, or just books that explore the rich beauty and tradition of the church.

Something philosophically explorative that could be considered a kind of love letter to the church/faith but not too heavy for late night reading.

Thank you for your recommendations!
