What is the Custom of Your Grief? by Timberlake Wertenbaker features an English schoolgirl who is befriended online by an Afghan girl after her brother is killed while on active duty in Afghanistan.

The play is taken from Women Centre Stage; a collection of eight short plays, commissioned and developed as part of the Women Centre Stage Festival, that together demonstrate the range, depth and richness of women's writing for the stage.

Selected by Sue Parrish, Artistic Director of Sphinx Theatre, these plays offer a wide variety of rewarding roles for women, and are perfect for schools, youth groups and theatre companies to perform. Other writers included in the collection include Winsome Pinnock, Rose Lewenstein and April De Angelis.
