Create a finished 2:3 portrait thriller book cover. Render only these exact text lines, spelled correctly: at the top, small refined uppercase “A THRILLER”; the dominant title, split across two lines as “SPLINTER” and “HOUSE”; near the bottom, “EVERY CRACK LEADS HOME.”; and at the foot, smaller spaced capitals “MARA VOSS”. Keep all text crisp and legible, with no other lettering. Build the title from bold, condensed uppercase display letters with broad solid strokes and tight spacing. The letterforms are real transparent glass, fractured by a single sharp impact within each letter: radial spiderweb cracks, large mostly flat central shards, smaller facets tilted outward, and a few fine splinters suspended just beyond the edges. Show clear transmission through the glass, deep optical depth, bright white edge highlights, and tiny concentrated glints at crack intersections. Use subtle blue-green only along thick shard edges. Preserve the title’s silhouette and readability; fractures must not obscure the words. Set the scene in a pale lavender-blue glass house interior: a quiet, empty hallway receding toward a narrow, unlit doorway, with a tall fractured glass window beside it. Let the background remain visible through the title. Soft diffused backlight passes through the glass, with gentle frosted diffusion only at select edges and soft caustic patterns cast beneath the letters. Keep the atmosphere cool and eerily calm, not dark or dramatic; use precise negative space, fine haze, and a few floating glass splinters. No gore, people, or extra objects. Composition: small eyebrow near the top; huge two-line title centered in the upper-middle, occupying most of the cover width; the hallway and broken window remain visible around and behind the title; tagline centered in the lower zone; author name anchored at the bottom. Restrained premium thriller-cover finish, high contrast between luminous glass and muted lavender-blue surroundings.
