The take-over friend

"On the second day of ninth grade, introverted Frances meets Sonja, a wildly funny newcomer from France, and the girls form a fast friendship. Frances adores Sonja's worldliness, and Sonja adores Frances's family, especially her older brother, Will. Frances and Sonja immediately declare themselves 'The Poets' and rally their homeroom to enter the homecoming parade with a poetry-mobile built from Frances's father's old band bus. But respective family crises begin to escalate, and tensions come to a head when Sonja temporarily moves in with Frances's family--forcing each friend to decide how close is too close"--OCLC.
