Crow Lake by Mary Lawson

Crow Lake was just as wonderful as A Town called Solace. Once again, Lawson created a cast of flawed characters I fell in love with and set them in a perfect place and time. Mystery, family secrets, humour, and descriptive prose. I was sad to turn the last page.

From the back

Orphaned young, Kate Morrison was her older brother Matt's protégé, her curious fascination for pond-life fed by his passionate interest in the natural world. Now a zoologist, she can identify organisms under a microscope, but seems blind to the tragedy of her own emotional life. She thinks she's outgrown her family, who were once her entire world - but she can't seem to outgrow her childhood or lighten the weight of their mutual past.
