I’ve enjoyed everything I’ve read by Lissa Evans, including her children’s books.
Our book group recently read ‘The Pull of the Stars’ by Emma Donoghue, author of ‘Room’. It’s set in a Dublin maternity hospital in 1918 (I think), when the flu epidemic is raging. All our group found it an absorbing read though the obstetric procedures may make you squirm!
I also enjoyed ‘Duckling’ by Eve Ainsworth, who has written a number of books for young adults - this is her first adult one.
‘The Vanishing of Esme Lennox’ by Maggie O’Farrell, is another good read, though written a while back so some of your group may have read it.
