Personally, I prefer Russian classics, which are aesthetic, gorgeous, inspirational and strong, suitable for boys. European classics are boring and awkward, and they are not as gorgeous as Russian writing.
If you think these masterpieces are too vulgar or too light, and want something special as a prize, then I suggest choosing some classic and collectible novels or poems. For novels such as Turgenev's First Love, I personally suggest that the first prize can be Tennyson's Selected Poems, which is profound and mysterious enough to be collected for 10 years.
Turgenev's "First Love", you will never find such beautiful words (I hope you can find a good translation, and even the best masterpieces will be destroyed by translation)
If Tennyson's Selected Poems were me, it would be enough to read only the outside of the book, not to mention the contents inside.
