I'll have finished reading this novel by the time you come tomorrow.
Literal
Tomorrow honorable-come-become [until-までには], this novel [object-を] read-finish [in-advance-ておく] [polite-ます].
おみえになる is a full honorific form — a special keigo for 来る ('to come'). The お~になる construction plus the verb 見える (literally 'become visible') combines into 'honorable visible-become' = 'come (of a respected person).' 読み終える is a compound ('read' + 'finish') meaning 'finish reading.' ~ておく projects preparation into the future. Elegant and deferential — the speaker prepares ahead of a superior's arrival.
