In addition to her output as a journalist, Rampersad has written two books. The first, Finding A Place: IndoTrinidadian Literature (Kingston, Jamaica: Ian Randle Publishers, 2002) explores, among other things, the relationship between journalism and fiction in West Indian literature, tracing antecedents to the works of authors such as Seepersad Naipaul, V. S. Naipaul, Samuel Selvon, Ismith Khan and Dennis Mahabir, among others. The book is a ground-breaking study that gives context to much of V. S. Naipaul's perspectives on colonialism, the Caribbean and Trinidad and Tobago, placing his writings within the context of some 200 years' gestation in Trinidad and its peculiar social, economic, political and literary evolution. Rampersad argues that the society's complex oral and literary antecedents propelled his acclamation as a 20th-century Lord of the English language and that early experiences of journalism on the island experienced by him and his predecessors, including his father Seepersad Naipaul, legislator/authors as F. E. M. Hosein, Dennis Mahabir, and near contemporaries such as Samuel Selvon and Ismith Khan, influenced their leanings towards expanding the literary tradition in social realism tradition.
In Finding a Place, Rampersad challenges and rejects the notion of the term East Indians to describe people in Indian heritage in the Caribbean, and traces their migration and adaptation from hyphenated isolation inherent in the description Indo-Trinidadian or Indo-Caribbean for the unhyphenated integration into their societies as IndoTrinidadian and IndoCaribbean that embraces both their ancestral and their national identities.
Rampersad is also the author of Through the Political Glass Ceiling - Race to Prime Ministership by Trinidad and Tobago's First Female, which examines the role of gender, culture and rurality in the success of Kamla Persad-Bissessar as the first female Prime Minister of Trinidad and Tobago in the country's general elections of 2010.
