Lisa Gardner if you like crime/whodunnit - quite graphic so not exactly bedtime reading but I can't put them down once I start! I've just discovered Kathy Reichs - also whodunnit type but from the anthropological side. Maeve Binchy is much more light-hearted, easier to read at bed-time. Tori Hayden writes about her work as a teacher of 'special needs' children. Also Philip Pullman's His Dark Materials trilogy, although written for children (Northern Lights, the 1st book, won the Carnegie Medal for childrens fiction in 1995 & was selected in 2007 as one of the 10 most important childrens books of the last 10 years), it is an excellent read.
Hope you find something you like
