What you have written is a noun phrase with a relative clause. (Since it's not a complete sentence, it doesn't have a main verb.) The complete sentence could have been something like this:
"This book is written in a style strongly reminiscent of Virginia Woolf’s novels."
The noun phrase in your question consists of the noun 'style' modified by the relative clause '[that is] strongly reminiscent of Virginia Woolf's novels'. The linking phrase 'that is' has been omitted for stylistic purposes, but is understood. So the meaning of the complete sentence would be:
"This book is written in a style [that is] strongly reminiscent of Virginia Woolf’s novels."
Here are some similar examples, in complete sentences:
She uses language [that is] absolutely typical of American teenagers.
Beside the road there was a ditch [that was] both deep and wide.
He made his fortune selling products [that were] neither useful nor attractive.
They have published a document [that is] utterly devoid of meaning.
