David Sedley's Lucretius and the Transformation of Greek Wisdom uses the eponymous Roman poet's work, largely intact, to reconstruct the lost writings of Epicurus (most importantly for Lucretius, Epicurus' thirty seven scrolls On Nature). But that's Cambridge University Press.
Thank you, Joshua, maybe. Sedley does reconstruct Epicurus' work. My memory may well deceive me, I have in mind a more detailed book, but Sedley's book is enough for me (for the moment)
