“This book came out of years spent learning to be a writer, a process that will never be complete,” Maggie Shipstead writes in the acknowledgments of her first story collection, You Have a Friend in 10A. It may sound over-earnest – indeed, the whole section does – but with Shipstead there’s always a sharp layer of self-awareness just beneath the surface. In this case, it works as a knowing wink to the reader, since the second story in the book, Acknowledgements, is narrated by a solipsistic young male writer as he considers how best to use his novel’s acknowledgments to air long-held grievances against former mentors and women who’ve turned him down.
