Review the item:
Wendy red each Cliff's Notes title on the rack, hoping to spot Moby-Dick. She finally found a booklet stuffed among the guides to Hamlet and bought it without regret, for she could not stomach another minute of the exhausting novel.

The first verb, red, is the problem. The sentence requires the simple past. Read (pronounced the same as red) is the correctly spelled form.

Bought, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
