A reading promotion aimed at young adults will be successful if the books selected to go into the promotion have a specific appeal to that age group; paperbacks which look cool and contemporary gathered together in a face-on display are guaranteed to draw the readers you're after.
Topping this off with a big sign - Teenage reads - will kill it stone dead! Teenagers won't want it because they don't want to be identified with a 'teenage' audience and older readers won't want it because they'll think the books are too young for them. The only readers who will clamour for the books are pre-teens desperate to read what their older brothers and sisters are reading.
Letting the books speak for themselves will get them issuing not just to the target group but to other readers who are drawn by an eye-catching display of intriguing titles.
Avoid any labels which narrow the target audience too prescriptively - Clear Choice will appeal more broadly than Large Print or Books for Visually Impaired Readers.
