The bread of heaven

Kate Gray has been writing about hungrily reading "Take this Bread" by Sara Miles. It sounds great but I'm not sure I'm going to find it at the next railway station bookstore I go through in Switzerland or Germany.
Communion is an important part of faith - speaking to the parts other faith practices don't reach. Church structures, good or bad preaching, committees, teaching, fellowship, power struggles, rituals, hymn-singing ... may come and go, but communion - this crumbly, messy, spillable covenant in bread and wine will continue to sustain faith in the breadbreaker God.
