i lost love sonnet :(

i need it to find nymph of love, but i dont have it in my items. i saved the girl in Candar from marriage and i think she gave me the sonnet, but now i dont have it. i could accidently sold it in the shop.. dont remember that, but cant think of any other explanation.. that girl is gone from Candar now.
Is there any other way that i can go to that seacret garden..? it would be not so fun to end game like that
