Who is the author of the speculative fiction novel "Half of What I Say"?

Introduction / Context:
Here the question tests familiarity with newer Indian English fiction, especially speculative literature. "Half of What I Say" is a novel that combines political, social, and speculative elements and has been shortlisted for literary prizes. Recognising Anil Menon as its author is useful for aspirants who want to keep up with contemporary Indian writing beyond the most famous names.

Given Data / Assumptions:

- The title in question is "Half of What I Say".

- The options list authors connected to Indian writing.

- Only one author is actually known in association with this speculative novel.

- The question needs a direct match between the book and its writer.

Concept / Approach:
The concept here is to recognise Anil Menon as a leading writer of speculative fiction from India. "Half of What I Say" examines politics, gender, and media through an imaginative narrative. The other options, such as KR Meera and Namitha Gokhale, are significant authors but are associated with different works, while Shashi Tharoor is mainly a non fiction and political writer. Knowing the genre and style helps narrow down the choice to Anil Menon.

Step-by-Step Solution:
Step 1: Recall that Anil Menon is often mentioned in discussions of Indian speculative and science fiction. Step 2: Remember that "Half of What I Say" has been described as speculative fiction, focusing on social change and narrative play. Step 3: Compare with KR Meera, who writes powerful literary fiction, usually in Malayalam and translation, but not this title. Step 4: Note that Namitha Gokhale is known for works such as "Paro" and for organising literary festivals, and that Shashi Tharoor writes essays and political non fiction, not this novel, leaving Anil Menon as the correct option.

Verification / Alternative check:
Verification can be done by recalling that book reviews of "Half of What I Say" consistently refer to Anil Menon by name and mention its shortlisting for literary prizes. Reference sites and catalogues list the title under his bibliography. Since none of the other authors are recorded as having written a novel with this exact title, there is no ambiguity once these details are remembered.

Why Other Options Are Wrong:
KR Meera is an acclaimed author but her major works have different titles, often translated from Malayalam.
Shashi Tharoor focuses on political commentary and historical writing rather than speculative fiction novels like this one.
Namitha Gokhale is a fiction and non fiction writer, yet she is not the author of "Half of What I Say".

Common Pitfalls:
A common error is assuming that any politically flavoured novel must be written by a well known political figure such as Tharoor. Another pitfall is simple unfamiliarity with newer names in Indian literature, leading to random guessing. Adding a small list of contemporary speculative and prize shortlisted novels and their authors to one's study notes helps reduce this risk.

Final Answer:
The speculative fiction book "Half of What I Say" is written by Anil Menon.
