in the plot section mike de wolf and horace hackett should be referred to by either their last name or first name you refer to the former by his first name and the latter by his last name in the plot section up there god is this an em dash or en dash in the genres section roland j green of the chicago sun times also described the work as a classic and wrote positively of hubbard's novel final blackout i don't think that final blackout is relevant here in the reception section typewriter in the sky which first appeared in unknown in is widely considered to be one of his best works you may have misquoted this because the period in the middle of the sentence seems odd in the influence section i bet if l ron hubbard had written purple rose of cairo they'd have given it a hugo i mean it is sort of a hip updated version of typewriter in the sky is purple rose of cairo and typewriter in the sky italicized in the corresponding reference
