Geometry of Sisters is out in paperback, and I'm so happy to revisit the characters Beck, Travis, Pell, and Lucy. They, and this novel where they first began, are very dear to my heart. Two sets of sisters converge at boarding school in Newport, Rhode Island, each lost in her own way. A reader recently wrote me, "I just read Geometry of Sisters and loved it—your descriptions of Beck's relationship with math totally blew me away." I so appreciate that she "got it." Because Beck and Lucy use geometry with such creative, magical logic—to try to regain what they most love.

Pell and Travis have no need of geometric help to find first love, forbidden by the school, but how do you stop a freight train?

Beck and Travis's mother Maura has been long estranged from her sister Katharine. There's almost nothing worse or more unthinkable, and writing their scenes both touched something painful in my heart and made me believe in possibility and goodness.

It's strange, because although I didn't love math in school, I felt something about geometry. The spatial plane, invisible connections. Researching this novel, I rediscovered the poetry and beauty of geometry. Don't think of it as math; think of it as a set of equations leading to love.

If you enjoy the characters in this novel, please read their continuing story in The Deep Blue Sea for Beginners...
