We need to output JSON with keys: summary, category, article_html. Article must be in HTML, with exactly one H1 at start with primary keyword. Primary keyword likely "best books to read all time India" or "best books to read all time India". H1 must contain that. We need 5-7 H2 main sections, H3 subsections. Each section: 2-3 p tags, each 100-150 words. That's a lot of words. 5-7 sections * 2-3 paragraphs * 100-150 words = 10-21 paragraphs * 100-150 words = 1000-3150 words. Minimum 1500 words. We can aim around 1700-2000 words. Each paragraph 120 words average, 12 paragraphs ~ 1440 words. Need 1500 min, maybe 13 paragraphs ~ 1560. Good. We must include UL/OL lists with 5-10 items. Use strong tags for key terms. End with 3-5 FAQ questions as H3. So after last H2, add H3 FAQ questions. We need to include specific book recommendations, authors, key takeaways. Provide lists. Also must include category: "howto". Summary 150-160 chars. Let's craft summary: 150-160 characters. Something like: "Discover the definitive list of India's greatest books ever written, with detailed reviews, author insights, and key takeaways for every reader." Count chars: Let's count. "Discover the definitive list of India's greatest books ever written, with detailed reviews, author insights, and key takeaways for every reader." Count: I'll count manually: "Discover"(8) space=1 total9, "the"(3)=12 space=13 "definitive"(10)=23 space=24 "list"(4)=28 space=29 "of"(2)=31 space=32 "India's"(6)=38 space=39 "greatest"(8)=47 space=48 "books"(5)=53 space=54 "ever"(4)=58 space=59 "written,"(8)=67 space=68 "with"(4)=72 space=73 "detailed"(8)=81 space=82 "reviews,"(8)=90 space=91 "author"(6)=97 space=98 "insights,"(9)=107 space=108 "and"(3)=111 space=112 "key"(3)=115 space=116 "takeaways"(9)=125 space=126 "for"(3)=129 space=130 "every"(5)=135 space=136 "reader."(7)=143. 143 chars. Need 150-160. Add more words: "and timeless wisdom." Add that. So new sentence: "and timeless wisdom." That's 21 chars (and=3 space=4 timeless=12 space=13 wisdom.=19?). Let's recalc: after previous 143, space=144, "and"(3)=147 space=148 "timeless"(8)=156 space=157 "wisdom."(7)=164. 164 chars. Slightly over 160. We need 150-160. Let's adjust: maybe remove "timeless". Recalc: After 143, add space=144, "and"(3)=147 space=148 "wisdom."(7)=155. That's 155 chars. Good. Ok summary ready. Now article_html: Build HTML string. We need exactly ONE H1 at start with primary keyword. H1: "Best Books to Read All Time India". That's primary keyword. Good. Then H2 sections. Let's plan 7 H2 sections: 1. Classic Indian Literature, 2. Modern Indian Novels, 3. Indian Poetry & Short Stories, 4. Indian Non-fiction & Biographies, 5. Indian Spiritual & Philosophical Works, 6. Indian Children's & Young Adult Literature, 7. How to Choose & Read These Books. Each section will have 2-3 paragraphs. Paragraph length 100-150 words. We'll write 3 paragraphs each for 7 sections = 21 paragraphs. That's 21*120=2520 words. Fine. But we also need FAQs at end with H3. That adds maybe 4 Q&A paragraphs each 2-3 sentences. That adds ~200 words. So total ~2720. Good. We also need UL/OL lists with 5-10 items. In each section maybe include a list of books. Use strong tags for key terms like book titles, authors. Also must use strong for key terms. Also include specific book recommendations, authors, key takeaways. Let's start building. H1:

Best Books to Read All Time India

H2: "Classic Indian Literature" Paragraph 1: about importance of classics, mention e.g. "The Mahabharata", "Ramayana", "Gita", "Garhwal", but those are epics. Could mention "Amar Chitra Katha". But maybe better: "The Mahabharata" etc. Provide overview. Paragraph 2: list of recommended classics. Use UL list: 5 items. Paragraph 3: key takeaways on reading these. Similarly other sections. Let's craft paragraphs ~120-130 words. We'll write them carefully. We need to ensure each paragraph 100-150 words. Let's count approximate words. Paragraph 1: maybe 120 words. We'll approximate. We have to produce final JSON with article_html string. Must escape quotes properly. Use double quotes for JSON string, but inside HTML we must escape double quotes. It's easier to use single quotes for attributes in HTML or escape double quotes as \". Use single quotes for attributes to avoid escaping. Also ensure no markdown. Let's craft article_html content. We'll produce article_html as a single string. We'll use \n for newline? It doesn't matter but we can include newline. It's fine. But we must ensure valid JSON string. So we need to escape newlines? In JSON, newline characters must be escaped as \n. But we can include literal newline as \n. Let's just put \n in string. Example: "article_html": "

...

\n

...

..." But the JSON string may contain line breaks; we need to escape them. It's easier to keep everything on one line. But readability wise, we can keep \n. We'll escape each newline as \n. Also escape double quotes inside HTML. We'll use single quotes for attributes to avoid escape. Also strong tags use . Let's start writing. We'll write article_html content:

Modern Indian Novels

... But we need UL/OL lists inside sections. We'll embed list within paragraph maybe or after paragraph. We must keep H3 subsections: For each section, we can add H3 for subsections like "Key Titles" maybe. But we only need H3 for subsections. We can add an H3 under each H2 for
