I call it serendipitous when two or more books that I’m reading at the same time or in quick succession have something pretty bizarre in common. Because I have so many books on the go at once – usually between 10 and 20 – I guess I’m more prone to such incidents. I also post these occasional reading coincidences on Twitter. (The following are in rough chronological order.)

• A Wisconsin setting in three books within a month (Shotgun Lovesongs by Nickolas Butler, This Is How It Always Is by Laurie Frankel and Crossing to Safety by Wallace Stegner)

• I came across a sculpture of “a flock of 191 silver sparrows” in Dear Edward by Ann Napolitano while also reading Silver Sparrow by Tayari Jones.

• Characters nearly falling asleep at the wheel of a car in Crossing to Safety by Wallace Stegner and In the Dream House by Carmen Maria Machado

• There’s no escaping Henry David Thoreau! Within the span of a week I saw him mentioned in The Library of Ice by Nancy Campbell, The Snow Tourist by Charlie English, Losing Eden by Lucy Jones and Crossing to Safety by Wallace Stegner. Plus I’d just read the whole graphic novel Thoreau and Me by Cédric Taling.

• Discussions of the work of D.H. Lawrence in Unfinished Business by Vivian Gornick and The Offing by Benjamin Myers

• That scientific study on patient recovery in hospital rooms with a window view vs. a view of a brick wall turns up in both Dear Life by Rachel Clarke and Losing Eden by Lucy Jones.

• The inverted teardrop shapes mirror each other on these book covers:

• Punchy, one-word titles on all these books I was reading simultaneously:

• Polio cases in The Golden Age by Joan London, Nemesis by Philip Roth and Crossing to Safety by Wallace Stegner

• An Italian setting and the motto “Pazienza!” in Dottoressa by Susan Levenstein and Crossing to Safety by Wallace Stegner

• Characters named Lachlan in The Ninth Child by Sally Magnusson and The Inland Sea by Madeleine Watts

• Mentions of the insecticide Flit in Nemesis by Philip Roth and Sacred Country by Rose Tremain

• A quoted Leonard Cohen lyric in Traveling Mercies by Anne Lamott; Cohen as a character in A Theatre for Dreamers by Polly Samson

• Plague is brought to an English village through bolts of cloth from London in Year of Wonders by Geraldine Brooks and Hamnet by Maggie O’Farrell; both also feature a woman who is a herbal healer sometimes mistaken for a witch (and with similar names: Anys versus Agnes)

• Gory scenes of rats being beaten to death in Hamnet by Maggie O’Farrell and Nemesis by Philip Roth

• Homemade mobiles in a baby’s room in A Theatre for Dreamers by Polly Samson and Sacred Country by Rose Tremain

• Speech indicated by italics rather than the traditional quotation marks in Pew by Catherine Lacey and Red at the Bone by Jacqueline Woodson

What’s the weirdest reading coincidence you’ve had lately?
