Léete el prólogo esta noche y mañana me cuentas si la contraportada dice la verdad.

Because this is an affirmative command in Spanish, the object pronoun gets attached to the end of the verb.

• lee = read
• te = yourself / for yourself
• léete = read it yourself / have a read

Here, te does not mean the person is literally reading themself. It is part of the very common pronominal use of leer: leerse. In everyday Spanish, leerse often suggests reading something through, reading it properly, or getting through it.

So léete el prólogo sounds more natural and a bit more expressive than just lee el prólogo.

The accent mark is there because when the pronoun te is attached to lee, the stress pattern changes in writing.

Without the pronoun:

• lee

With the pronoun:

• léete

Spanish adds the written accent to keep the correct pronunciation stress. This is very common with affirmative commands plus attached pronouns.

Both can mean read the prologue, but léete adds a nuance.

• lee el prólogo = read the prologue
• léete el prólogo = read the prologue through / give the prologue a read / read it for yourself

In Spain, leerse is very common when talking about reading books, articles, etc. It can make the sentence sound a bit more natural, colloquial, or complete.

Spanish often uses the definite article where English might not.

So:

• léete el prólogo = read the prologue

Even if English might sometimes say read the prologue or simply read the prologue tonight, Spanish normally wants the article here: el prólogo.

Yes. In this sentence, esta noche means tonight.

Literally, it is this night, but in natural English the best translation is just tonight.

Spanish very often uses the present tense to talk about a future action, especially when the time is already clear.

• mañana me cuentas = tomorrow you tell me / tomorrow you can tell me
• mañana me contarás = tomorrow you will tell me

Both are possible, but mañana me cuentas sounds very natural and conversational. It can also feel slightly like an instruction: read it tonight, and tomorrow tell me...

Literally, it means you tell me.

The verb is contar, which can mean:

• to tell
• to recount
• sometimes to count, depending on context

Here it means to tell.

• me = to me
• cuentas = you tell

So mañana me cuentas means tomorrow you tell me or more naturally tomorrow let me know / tomorrow tell me.

Because si without an accent means if or whether.

• si = if / whether
• sí = yes

In this sentence, si la contraportada dice la verdad means whether the back cover tells the truth.

Because here si introduces an indirect yes/no question, meaning whether.

• me cuentas si la contraportada dice la verdad = you tell me whether the back cover is telling the truth

After verbs like decir, contar, preguntar, ver, saber, etc., si often introduces an indirect question, and the indicative is normally used.

So dice is exactly what you would expect here.

Contraportada usually means the back cover of a book.

In context, it often refers not just to the physical back cover, but to the text on the back cover as well — the short description or blurb that tries to sell the book.

So here, si la contraportada dice la verdad really means something like:

• whether the blurb on the back cover is accurate
• whether the back-cover description is telling the truth

This is just normal personification, and it works the same way in English.

• decir la verdad = to tell the truth

Here the back cover stands for the claims made in its text. So the idea is:

• Does the description on the back cover accurately represent the book?
• Is the blurb honest?

It is not literally saying the book cover speaks.

Because Spanish can leave it understood from the context.

A fuller version might be:

• mañana me cuentas eso
• mañana me cuentas si la contraportada dice la verdad

The whole si... clause gives the content of what you are being asked to tell. So nothing else is necessary.

It sounds very natural in Spain, especially because of léete.

That structure is not exclusive to Spain, but in Peninsular Spanish, using leerse for reading a book or part of a book is very common:

• Me leí la novela en dos días
• Léete el primer capítulo

So for a learner focusing on Spanish from Spain, this is a very useful pattern to notice.
