We need to write an article about best books to read this summer 2026. Must produce JSON with keys: summary, category, article_html. The article must be at least 1500 words (within HTML). Must have exactly one H1 at start with primary keyword. H2 for 5-7 main sections, H3 for subsections. Each section: 2-3 paragraph
tags, each 100-150 words. That's heavy. We need to produce 1500 words. Let's calculate approximate words: 1500 words / 6 sections (H2) = 250 words per section. Each section has 2-3 paragraphs of 100-150 words, so 200-450 words. Good.
We need to include book recommendations, authors, key takeaways. Include UL/OL lists of 5-10 items, use strong tags for key terms.
End with 3-5 FAQ questions as H3.
No markdown, no code fences. Must return only JSON.
Let's craft the article. Primary keyword: "best books to read this summer 2026". H1: "Best Books to Read This Summer 2026".
H2 sections: maybe 6 sections: 1) Must-Read Fiction, 2) Inspiring Nonfiction, 3) Young Adult Gems, 4) Sci-Fi & Fantasy Escapes, 5) Cozy Mysteries, 6) Literary Classics for the Season.
Each section will have 2-3 paragraphs (p tags). We'll need to keep each paragraph 100-150 words. Let's approximate 120 words each paragraph. 2 paragraphs = 240 words. That's okay.
We need UL/OL lists inside sections, maybe inside paragraphs or separate. We'll include UL list of 5-7 books for each section.
We need to include strong tags for key terms.
We need at end H3 FAQs: 4 questions.
We must produce article_html as a string. Must escape quotes properly. Since we output JSON, we need to escape double quotes inside the string. Use \".
Let's craft the article.
We must ensure HTML is valid. We'll wrap article in tag maybe.
Let's outline:

But requirement: End with 3-5 FAQ questions as H3. So we can have H3 for each question. Each question can be H3 and answer in . That might be simpler.
Let's produce 4 FAQs.
Need to keep article length 1500+ words. Let's approximate: each section: 2 paragraphs + list. Paragraph ~120 words each => 240. List items maybe 10 words each, 5 items => 50. So each section ~290 words. 6 sections => 1740 words. Good.
We must watch for word count. Let's craft actual paragraphs.
We'll generate content. Use strong tags for key terms like "summer reading", "must-read", "author", etc.
Let's craft the first paragraph for Must-Read Fiction:
Paragraph 1: talk about selecting fiction, warmth, etc. 120 words.
Paragraph 2: highlight the list.
Let's begin writing.
We'll need to escape quotes in JSON. We'll use single quotes inside HTML content if needed? But double quotes in attributes must be escaped. We can use single quotes for attributes, but JSON requires double quotes for outer string. We can use single quotes inside string without escape. For example:
It’s a sunny day...
fine. For HTML attributes, we can use single quotes: 
but we may not need attributes. For lists, we don't need attributes. So we can keep plain text inside.
We just must ensure JSON string uses double quotes for keys and outer string. Inside we must escape any double quotes, but we might avoid them entirely. So we can use no double quotes inside article_html content.
We also should avoid double quotes inside the content. Use single quotes or no quotes. For example, in quoting a title we might use “Title” but that's curly quotes, not double quotes. So safe.
Now produce article_html string.
Let's craft.
I'll write each paragraph approximate 120 words. Let's count.
First paragraph Must-Read Fiction:
"Summer is the perfect time to dive into stories that transport you to distant lands, explore the depths of human emotion, or simply keep you company under the warm sun. This year’s best‑selling fiction offers fresh voices and timeless themes that resonate with readers of all ages. Whether you prefer a gripping thriller, a tender romance, or a literary masterpiece that challenges your worldview, the curated list below will satisfy every craving. From the bustling streets of a modern metropolis to the quiet corners of an ancient forest, these novels promise unforgettable journeys that will stay with you long after the last page is turned."
Count words: Let's approximate. We'll write more precisely. But okay.
Second paragraph Must-Read Fiction: talk about specific books.
We'll include list.
List items:
1. "The Midnight Library" by Matt Haig (2026 edition) – explore alternate lives.
2. "The Lost House" by Andrea McLean – mystery in a coastal town.
3. "Echoes of the Sea" by Maya Johnson – coastal saga.
4. "The Golden Compass" by Philip Pullman (reprint 2026) – etc. But maybe choose new releases 2026.
But the list should be 5-10 items. We'll include 6.
Ok.
Second paragraph: "Here are six standout titles that capture the spirit of the season..." We'll incorporate list.
Let's draft each section.
Important: Each paragraph 100-150 words. Let's aim for ~120 words.
We'll need to count roughly. We'll approximate.
We also need strong tags for key terms.
Let's proceed.
We'll produce final JSON string. We'll need to escape newline characters? JSON string can contain newlines but they must be represented as \n or actual line breaks? It's okay to include actual line breaks as part of string? In JSON, line breaks must be escaped as \n. But many outputs show line breaks. It's safer to keep single line string with \n. But we need to produce valid JSON. Let's produce article_html string with \n for readability but escapes. But we can just produce a single line string with line breaks encoded as \n. That might be easier.
Let's produce article_html string with \n representing line breaks and ensure quotes are escaped
